A small eyeglass workshop that focuses on frame manufacturing and does not branch out into other areas.

The eyewear industry in Sabae is said to have started when one girl was helped by eyeglasses and so the industry continues through passing down the theme of "helping". This theme can be seen through making glasses with consideration to metal allergies and by preparing sizes that can be worn by parents and children. In addition, by not dividing labor, we have established a workplace system in which the workers can help each other. We will make eyeglasses that are helpful to have at the manufacturing site where we help each other.

Plus Jack has also developed a disaster prevention whistle. A disaster prevention whistle which like an accessory made with eyeglass materials and techniques. Huh, it's a whistle!? It's so beautiful that that thought will come to your mind. The name of the whistle is "effe". Due to the fruits of technological capabilities, it is able to produce high notes even with a small lung capacity and drain water with a single swing.
