CONCEPT
This is an accessory made with epoxy resin and mainly created by sisters Yukiko and Mikako Tamaru.
These original accessories are made primarily from transparent resin parts with a combination of natural stones, glass beads, felt, and ribbon. One of the same designs looks slightly different because each one is handcrafted. Our concept is to create different designs and pieces that we would want to wear them, and people of all ages can perceive the beauty that lies beyond the accessory itself.

BIO
Born in Tokyo.
Grew up doing crafts such as knitting and sewing from a young age, partly due to parents who loved working with their hands.
In 1995, while my older sister was working as an office worker and my little sister as a stylist, we began making our own accessories as a hobby using Swarovski and glass beads. During that time, we started wanting beads with our own hues, shapes, floral patterns, and stripes. It wasn't until we thought of making them ourselves that we began making our own with epoxy resin. Afterwards, our products started selling in select shops and variety stores across the country.
April 14th, 1997 Established Tamaru Industries Co., Ltd.
September 3rd, 1998 PREMIERE CLASSE store opening.

1. Introduction
In making accessories, rarely do we draw our designs on paper beforehand. The reason for this is because we come up with the shapes and designs as we make the accessories. The few times we do draw out the designs prior to making it, is when we design metal parts of photographs or resin parts of main bodies. We ask a specialized metal processing company and stone-polishing craftsmen for their help, and they require designs and specifications. Production mainly divides into metal parts and resin parts.
2. Designing Resin Parts
Producing the resin parts is the most important process for Tamarusan. When resin is made, the first thing we do is name it. This becomes the series name. Hand-drawn pictures are the most common at Tamarusan. We print these designs on either paper or film, according to the texture of the design. In terms of the final product, the main difference is that it will turn out opaque when printed on paper, and translucent when printed on film. When printed on film, the film will reflect a glow the color of the metal fitting on the bottom, or conversely, the color may toned down, so it is important to proceed while observing the resin's compatibility with the metal fittings. Here, a printed piece of paper is used as a template and scissors are used to cut the paper to the size of the finished resin.
3. Producing Resin Part Prototypes
First, I will draw a design of the shapes of the resin parts I want to make. Next, I will have a stone polishing craftsman process it. Agate and onyx are used for prototypes. Relatively hard stones are selected for prototypes, so it can withstand the many times silicon molds are made from it. When there are many cuts in the stone, light reflects and shines brilliantly. In addition, the refraction of light will change the appearance of the inside pattern. On the contrary, dome shaped surfaces will provide a lens effect to enlarge the pattern on the bottom, so even if two pieces have the same design, if the shape is different, it will mysteriously have a completely different appearance.
4. Producing Pedestals for Putting in Resin
Producing Pedestals for Putting in Resin Molds are made with metal materials so they fit perfectly with each resin part. Materials used are copper, brass and silver. The entire reverse side is patterned with a design using a portion of Tamarusan's logo. Unevenness is attained by etching the pattern, allowing the pattern to clearly rise to the surface, especially when antique plating is applied.
5. Creating Silicone Molds
Silicone is used to make the molds. The stone prototype is pasted firmly at the bottom of the container, so it will not move even when silicone is poured in. The silicone is poured in quickly and little by little, in order avoid air bubbles from forming. It depends on the temperature, but it is usually left put for 1 day. Silicone molds become stretched after repeated uses, so they are discarded after 3-4 uses so beautiful resin parts can continue to be made. For larger items, such as resin for loop ties, there are cases when the molds can only be used once.
6. Pouring Resin Into the Mold
The base and the curing agent are mixed together well. Once it is warmed up with hot water, mixing becomes better and curing defects can be prevented. In order to further remove air bubbles, the silicone mold is placed on a hot carpet and warmed in advance. During the winter, work is done with the heating temperature set very high. Furthermore, applying hot air with a dryer makes it easier to remove the air bubbles. Because the temperature is higher in summer, it is easier to operate and there are less mistakes compared to winter. The resin is finally poured into the silicone mold. Because the mold is very small, there are times when the resin overflows or there is not enough. To solve this, a wire is used to even out the amount as a whole. Next, all the materials of the series, such as paper, film, beads, etc. is placed inside. Depending on the seasonal temperature, hardening time is 1 to 3 days.
7. Completion of Resin Parts
After a few days, the hardened resin is removed from the silicone mold. This is the completion of a colorful, original, resin part. I match these parts with different colored metals to see how I can bring out the most brilliant shine as I look towards my next creation.
8. Production of Metal Parts
During the production of the resin parts, there was no need for any direct fire, but in creating metal parts, a gas burner becomes necessary. No designs are pre-drawn here as well, and the production is done without rehearsal. First, in the case of a hairpin, start from where you cut the brass wire, and process the metal with the flame.
9. From Metal Polishing to Plating
Metals that are shaped with fire will oxidize, so we will get rid of the dirty portions by soaking in sulfuric acid. From there, it is polished carefully with a metal brush. After this, it is sent to the plating factory. If it is polished cleanly, the resulting plating will also come clean.
10. Assembly Work
When the metal parts come back from the plating factory, we begin the assembly process with the resin parts. The 5 main plating colors are "antique gold", "antique silver", and "antique bronze", 24 karat gold plating, and rhodium plating. In addition, nickel free plating which is less susceptible to metal allergy is used (excluding some). Depending on the resin series, the most suitable colors are selected. Blue types match well with antique silver and rhodium. Green and yellow types with antique gold or gold. Pink, red, and oranges match well with antique bronze and gold.
11. Finishing Touch
After the resin parts and metal parts are attached with an adhesive, matching natural stones or beads are selected. It is very interesting that they are made, the perfect stone or pearl for each series is naturally decided. This is how the world of one series will expand. As I explained in the introduction, because we do not draw our designs on paper, one of the major pleasures is the unexpected results we achieve in the end.
Let customers speak for us
from 22 reviewsI confirmed my order at 10:20 a.m. and was up in arms when I received an email at 10:48 a.m., just 28 minutes later, saying that the order had been shipped. Thank you very much for the explosively fast shipping that makes the express delivery of other major shopping site hazy. I don't think this is something that happens by chance. The products in this shop are of good taste. For example, the metal parts are not shiny but antique, and the originality of the company, which continues to make products that you can't see anywhere else, is, of course, wonderful. However, along with that, I can feel the pride of a merchant rather than just a jewelry designer, such as the extremely sincere response and the attention to detail in the products and packaging that arrived. I see that and I think that's really great. I think it's a delicate product, so I'm hesitant to use it often. However, I've been told that it will be repaired, so I'll continue to use it. I was able to get a nice tie pin.
It's very cute and makes going out fun.
I was looking for a bolo tie as a gift for my husband, but I couldn't find anything with a good design. When I was having a hard time, I found this product. The actual product has an exquisite nuance and texture, and the matching feeling of the leather straps and fasteners is wonderful. My husband, who is particular about fashion, is also very satisfied. The packaging was really nice too. In addition, it was helpful to have a smooth exchange with chat. Thank you for your prompt response.
"Too cute" She was very happy. I'm happy to hear that. The "Musical Note Series" seems to impress those who make music a profession or a hobby with its casual insistence on musical notes.
As the title says, when I come to work wearing this tie pin, people ask me where I bought it. Thank you very much for bringing to the world a product that is very hard to find in other stores. The company does not specifically ask me to wear a tie to work, but I wear a tie to work because I want to wear this tie pin. The downside is that it would be sad if I lost it. I will use it carefully not to lose it.
Thank you for the very fast shipping. It is my favorite hair accessory. I will treasure it.
It is a rare men's kanzashi. A little pricey, but I bought it because it is something I wear. It arrived in a wooden paulownia box. Its high quality can be recognized at a glance. It is quite well made and I like the geometric representation. My hair is not long enough to be held together by a kanzashi. Therefore, I put my hair in a bun and then insert it.
I bought this hairpin because I already had and loved the hair elastic and pendant from the "Tiger Beetles Series." It's cute and I'm glad I got it on sale. Thank you very much.
I buy a gift for my friend every year at "TAMARUSAN", and incidentally, I buy something for myself as well. I'm very satisfied with this uniquely stylish barrette. I also had them engraved with my initials. I am satisfied. Thank you for your kindness. I look forward to working with you again next year.
I gift my friend as a birthday present, a product from "TAMARUSAN" every year. She also wears a kimono, so she is very pleased with the blend of Japanese and Western styles. Her initials were engraved on it, so she said, "Every year, another treasure is added to my collection". I was happy to hear that. She matched it with green clothes the other day. It was lovely. I would like to thank TAMARUSAN for their courteous and professional service. I look forward to working with you again next year.
The "Backyard Series" is nice and chic. I will use the "obidome" as a hat decoration. It will be a nice accent.
I loved the design. The blue color matched my yukata.
I have been using it for a long time, and it is very helpful because the kanzashi does not lose its shape easily (other companies' products sometimes deform or break) and it stays in place even with long hair.
It goes well with both western clothes and kimonos. Also, the swinging "dangling ornaments" brighten up my mood.
"Not only the artwork, but also the packaging box and mizuhiki are stylish.
The packaging box and mizuhiki are also stylish.
I feel many times happier when I receive them.
The store is very meticulous and thoughtful..."
All of TAMARUSAN's accessories are carefully made and look like works of art....
Above all, they look great when worn. It's a wonder!
The smooth and shiny luster is beautiful, and the antique-like coloring that develops over time is also really wonderful.
Each series is so cute that I always have a hard time deciding which one to choose.
I have given them as gifts, and they have been very well received.
The wrapping is also tasteful and elegant, so you don't have to worry about giving it as a gift.
I think it is really luxurious to be able to buy directly from the creator.
Keep up the good work!
