Packed with mid-century style these fun, colorful coasters will make everyone smile (and you can set your drink on them while making a different drink using the instructions!). It's cocktail time somewhere! 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.
