Made in Japan Glass Cord This type of cord is inserted into the left and right temple sections of your glasses. When you're not wearing your glasses or sunglasses, you can hang them around your neck, and when you are wearing them, the cord adds a stylish touch around your face. Regardless of its use, you can also use it as an accessory. Cord Color: Green (GN) Cord Length: 700mm (Width 7.5mm x Thickness 1.5mm) Cord Material: Acrylic Weight: 4g This is a convenient glass cord for sunglasses and eyeglasses. I purchased it for about 2,500 yen, but I only used it once and have been storing it since then.
