This listing is for an item that will be fullfilled by a partner with the drop shipping company I use, Printify.  This artwork is my original piece, but I am not involved in the production of this item, only in it's design.  This coaster is an awesome way to enjoy a piece of art in a tiny, functional and affordable way.
