This is the JAPONISM JN-471, col.03, a slim frame with a sharp lens shape in a brown color. Made by the long-established company Boston Club Co., Ltd. in Sabae City, Fukui Prefecture, the home of eyeglasses, using original fabric specially ordered from the Italian company Mazzucchelli, it features a very beautiful color. Mazzucchelli is the world's leading acetate (plastic) manufacturer, providing fabric to world-renowned eyewear brands such as Alain Mikli and Beausoleil. Only a limited number of manufacturers can place special orders with Mazzucchelli, and Boston Club is one of them. This Mazzucchelli-made fabric has an Amazon color, a very beautiful color with green and yellow mixed into a brown base. When you hold it up to the light, it's very beautiful and makes you swoon ^^ This model is equipped with a "cuff spring," JAPONISM's unique spring, in the yoke (the part of the glasses that connects the lens frame to the temples. This is the part of the glasses that is most susceptible to stress due to the opening and closing of the temples). (I think the idea is similar to 999.9's reverse R-hinge). This cuff spring is made of expensive β-titanium, and thanks to this part, even for me, who has a wider face, the pressure on my temples became softer, and I was able to get a more comfortable fit. At the same time, this titanium part also reduces the stress on the eyeglass frame itself while also serving as a design accent, and I think it's very cool. In particular, the front parts, which were created by Aoyama Megane Co., Ltd., which has the unique technology of hydraulic pressing in Japan and can freely bend acetate, are combined with this cuff spring, creating a flowing design from the front to the temples, and I really liked it. (Thanks to these parts, I feel like it gives my face depth and has a slimming effect ^^) I own nearly 30 pairs of glasses at all times, and I haven't used this one much recently, and the storage space has reached its limit, so I'm reluctantly putting it up for sale. I would be happy if I could sell it to someone who likes it and will take good care of it.
