This is a set of 44 buttons. The inside of the gold frame appears to be a reddish-brown color (not bright red, but can look vermilion or pink depending on the light...). These are new and have been stored in a box for about 20 years, but I think they are in good condition. The retail price was 15,640 yen. 25mm: 12 pieces (retail price 500 yen/piece) 20mm: 8 pieces (retail price 350 yen/piece) 18mm: 12 pieces (retail price 310 yen/piece) 15mm: 12 pieces (retail price 260 yen/piece) Please refrain from purchasing if you are sensitive to items stored at home. Returns are not accepted. Thank you for your understanding.
