Set of 12 colorful mosaic design coasters. - Quantity: Set of 12 - Design: Mosaic pattern - Diameter: Approximately 9cm These coasters have been stored in a warehouse for about 20 years. I believe they are from 30 to 40 years ago. They are unused, but I washed them by hand because they were dusty. The box has stains and a musty smell. They have a Showa retro design that is no longer available, so would anyone like them? I am also selling other coasters. Thank you for looking.
