Set of 36 buttons. Silver frames with black interiors. The black areas also appear to have hints of gray or blue. These are new and have been stored in a box for about 20 years, but I think they are in good condition. The original retail price was 12,720 yen. The 18mm buttons don't seem to be in the best condition, so I will include them for free. 21mm: 24 pieces (original price: 380 yen/piece) 18mm: 9 pieces (original price: ---- yen/piece) 13mm: 15 pieces (original price: 280 yen/piece) Please refrain from purchasing if you are sensitive to items stored at home. Also, returns are not accepted. Thank you for your understanding. I have several other colors available, so please inquire if you are interested.
