In world of eyewear, you be able to come across varied materials especially on plastic frames. The most commonly used are acetate and plastic molding materials.

Plastic molding material are generally used on the cheap eyewear which are easily distort, so we are not going to talk much about this. Acetate, also called the plate has good penetrability, glossiness and anti-ultraviolet. Furthermore, acetate has no sticky smell and it is easy to create various combinations by multi-level stacking, which create plenty of gorgeous effects – the natural vein, such like wood grain and tortoise-shelled turtle and so on. Because of the high-hardness and stable substance, it reaches its best stability by deacidificatimon and dry-off. Its hardness and polished gloss are as good as the crystal. However, this procedure requires at least three years, which lead to the high cost and usually adopted on high-class eyewear brand.

If you are an vintage lovers who only want “authentic”. Celluloid will be the choice. It is the earliest polyurethane material. Although this material is highly flammable, difficult and expensive to produce, manufacturer in Japan still love to use this for their exclusive handmade frames. We run across some colourful tales of claim that celluloid material are explosive! But let me asked you a question: “have you ever see a ping pong ball explode?” Neither have we. Ping pong balls are one of the few common everyday articles still made of genuine celluloid.  Celluloid is classified as a “Flammable Solid”, not as an explosive.  Some other common uses of celluloid today are in musical instruments, guitar picks and films. The true danger was the production process, not the finished product. Frame made of celluloid materials are more sturdy. And because of its individual handcrafted, it have becoming more and more well known. example like  frame from; Oliver people, Dita, Tarts and Tana-gokoro eyewear do produce frames with celluloid and many other makers.
