El Diablito (lil devil) printed from a hand carved linoleum block. 3.5" round paper coasters, sprayed with a bit of protective sealer so you should be able to use them more than once.
Part of La Sirena's 'Mexican Session' collection.
You might also want to pick up some sirena coasters. They look great together (see the photo), plus you only have to pay shipping on one item.
