This coaster was given to me as a souvenir from India in either 2015 or 2016. The illustrations and colorful artwork are cute, but the material might be difficult to wash. The back is cork, the surface feels like thin plastic that makes a clicking sound when you tap it with your fingernail, and as you can see from the side view, the middle appears to be cardboard. If it can't be washed, it might be better to display it on a wall instead of using it as a coaster. H9.4cm W9.4cm D4mm
