Fishing Coasters (Choose your 4!)Four 4"x4" coasters Choose 4 coasters from our Wilderness Collection! Any of these are also available as a 12"x7" sign on our website! Natural slate coasters, that we engrave ourselves, with rubber pads on the bottom. These coasters are a natural stone product. Chamfering (cutting a sloped edge) can cause chipped edges. They can vary some in thickness, color, edge shape, and texture. This is to be expected and not considered a defect.
