Trip (or, actually please don't fall) back in time to the glory days of Roller Skating with this fun, colorful set of coasters featuring vintage Roller Rink graphics. Each coaster set comes in a decorative wrapper (pictured) - for an easy, affordable ready-to-go gift! With an MDF base and a cork back every coaster is sealed with a waterproof, heat resistant resin (similar to that used to coat restaurant bars or tables) that provides a glossy finish and guarantees a long life. Handmade in the USA
