Silicone mold for creating alphabet, number, and symbol parts. I bought this about a year ago, but I probably won't use it, so I'm selling it. The size is approximately 20 cm x 13.5 cm. It's an opaque mold, so UV light may not reach and cause incomplete curing. Therefore, the use of two-part resin is recommended. I will ship it in an envelope. Thank you. #handmade
