Atleast get some brains in your coasters, each set of Cerebral Brain Coasters comes with ten glass coasters. Each coaster has four rubber feet (to further protect the surfaces the coasters are protecting in the first place) and a slice of brain printed on it. If you stack your Brain Specimen Coasters in the proper order, which is easy to do, since the coasters are labeled, and look from the proper angle, you’ll see a full brain.
