These Dino keychains are made of Epoxy Resin, an organic and food safe craft epoxy (similar to plastic). *colors may vary depending on screen type* All of my items are hand-made and resin crafting is a tedious process. If you see any minor imperfections, just remember your item was made by a human and not a machine. CARE INSTRUCTIONS: Due to these being made with epoxy do not leave in direct sunlight or extreme heat temperatures for an extended length of time.
