Made out of durable two part epoxy resin. The dominoes can be cleaned & sanitized. DO NOT use Alcohol based cleaners as they may ruin the resin. For continued care and long lasting shine we recommend using soap and water rather than alcohol based cleaners.
***IMPORTANT NOTE: Due to the nature of resin, small imperfections such as air bubbles may occur in each uniquely made set. However, I will do my best to minimize any appearance of air bubbles in the final making of products.***
