Topo Coasters are a set of four drink coasters which are used to represent the real topography of places from around the USA, like the Red River Gorge in Kentucky. They’re simply amazing.
Of course, you can’t tell by looking at them where the coaster is supposed to be representative of, but on the back of each coaster you’ll find a layer of veneer engraved with the geographic coordinates for the location that is on the front. Each coaster is made of cork, the extra absorbent and somehow quick-drying natural material. The coasters measure 4 inches and are just 1/4 of an inch thick. The Topo Coasters set is available now for $39. [Purchase]
