Even if he’s not a neat freak, these coasters will add some spirit and style to your dad’s favorite den. The sporty collection includes images related to Lions, Tigers, and Red Wings, oh my! You’ll also find options for Spartan, Wolverine, and Piston fans. Handmade using one of a kind Italian tumbled stone, each has a natural cork backing. They are designed to make liquids bead-up on the tile’s surface to protect the artwork from any fading and stainse. The tiles are roughly 4×4 inches and .25 thick. Get him one for his favorite team, or a set to suit every sports season.
