Blast back to the age of (long promised but never delivered) Jet Packs with these fun, retro Toy Robot drink coasters. The perfect gift for that collector or sci fi fan - a charming and colorful addition to any table. 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. Please Note: My coasters are made-to-order just for you.
