This dragon keychain uses color changing material, which has an array of colors from different angles, with a starlight shimmer throughout. If you plan to purchase multiple items from my store, I'll adjust the shipping costs after the sale is completed. The material used in this dragon is PLA (Polylactic Acid) which is a bioplastic that is produced from plant starches using a sustainable process. PLA is biodegradable under appropriate conditions and is generally regarded as food safe since it decomposes back into its lactic acid building blocks, which are non-toxic. NOTE: Some dragons have pointy edges that can be sharp. You can rub them against material like denim to dull them. Because of the pointy edges, not all dragons are suitable for small children. As with any 3D print, there will be on occasion some imperfections, this is completely normal.
