Set of 6 mosaic design wooden coasters. - Quantity: Set of 6 - Design: Mosaic pattern - Material: Wooden frame and ceramic - Colors: Blue, pink, yellow, gray - Size: Approximately 9cm in diameter 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 they were dusty, so I have hand-washed them. The box has stains and a musty smell. They have a Showa-retro design that is no longer available, so if you like them, how about it? Thank you for looking.
