Every time I work on these coasters I get the "Lets all go to the lobby" song stuck in my head. But, that aside, I really enjoyed putting together these nostagic coasters focusing on the good-ol'-days of going to the Drive In. Fun for movie-night or maybe a Father's Day present 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.
