Thank you for looking. This is a paper coaster I received at the Pompompurin Cafe several years ago. The back is white. It is approximately 9cm in diameter. The design features Pompompurin and Muffin eating watermelon. This is a long-term home storage item. I do not see any noticeable scratches, but please refrain from purchasing if you are sensitive. I will ship it using Yu-Packet Post Mini with measures to prevent water damage and folding. It will be shipped anonymously.
