A set of Gaming Surfaces with unique themes Mouse Pad material, a neoprene rubber backing with a water resistant, smooth surface Great for a gaming mat! 8 individual mats. These islands are 1mm thick and are designed to be used on top of a water themed FAT Mat (sold seperately). This island set matches our 'Caribbean' series of mats. While other gaming surfaces can be great, they have their limitations. Felt has hairs that catch models while moving and gets dirty easily, cloth creases and is plain, latex mats require painting and tear easily, wood surfaces are heavy, can be expensive and require a lot of work to prepare and paint. Plastic looks great, but dice bounce all over it loudly, it's expensive, you have to paint it, they're difficult to transport and they have seams running across them where the tiles meet. A game mat on a mouse pad would be durable but flexible, light, good looking, easy to use with no preparation needed, and reasonably priced!
