No true Transformers fan would set his drink down without using one of these Autobot coasters. Unless, of course, that Transformers fan favors the Decepticons -- then that slight is perfectly warranted.
The Autobot coasters were custom-made by Etsy crafter Polyester 10 out of recycled 1987 Marvel Autobots comics. The issue featured on the coasters is a favorite of Polyester 10's and features the Autobots led by Blaster (who?) fighting against an evil used car salesman. The coasters themselves are made out of one of the more durable materials around, rock, and are waterproof but not submersible. A set of five coasters will set you back a cool $17, which might be cheaper than what Paramount would charge for officially licensed coasters.
