Geometric green pattern - Accessories: Tweezers I believe this is a han-eri (collar) for a nagajuban (undershirt). I received it for my coming-of-age ceremony, but I didn't use it because I chose a different color. The box and tweezers show their age, but the collar is in beautiful condition. I don't think it has been used. It's a yellowish-green, like young grass, rather than the color in the photos. I would appreciate it if you could understand that it has been stored for a long time.
