Here's an American-style rubber coaster. Originally intended for placing glasses in a bar, it's also great for putting your keys on in your room, or just as a decoration. The American taste is nice! Even if you're not drinking alcohol, it's good for coffee at your desk! Regarding the size, it is an American (inch) standard size, so there may be some slight errors. Due to being an imported product, there may be changes in specifications such as size and design depending on the time of arrival. We will upload images each time, but please understand that there may be slight differences. Size: Approximately 9.5 x 9.3 cm
