Coasters purchased on a trip to Okinawa a few years ago. Shingaki Tile Factory Red Tile Coasters, Whale Shark Pattern One gray, one pink (I threw away the packaging, so I will wrap them in bubble wrap for shipping) I haven't used them much, so I think both the front and back are very clean. - Colors: Gray, Pink - Design: Whale Shark - Made in: Okinawa - Back: Non-slip Please refrain from purchasing if you are sensitive to used items, as they have been stored by a private individual.
