30 Coaster. This thirty coaster is modelled on the legendary Scrabble board game letter tile so you can celebrate a milestone birthday or anniversary in truly retro style. Thirty coaster is 10cm square with rounded corners, made from high gloss tough melamine that can withstand temperatures up to 140 degrees and backed with a hard wearing cork base to protect your surfaces. We recommend you do not put the coaster in the dishwasher but simply wipe clean instead.
