Hololive Butler Glasses Collaboration: Shirogane Noel Glasses *These are non-prescription, plastic fashion glasses. If you need prescription lenses, you will need to have them replaced. I opened them once to check them, but I haven't used the glasses since then, and they have been stored in a dark place, so they are in good condition. ■ Shirogane Noel Model Size: 49☐21-140 *Units are mm Frame Material: Stainless steel, nickel silver (alloy), acetate Lens Material: Plastic Set Contents: Eyeglass frame, original eyeglass wipe, original eyeglass case
