This is a food safe plastic handmade mold. no mold release is needed. This mold is a 4 cavity mold- this mold features 4 1 1/2" Kawaii little unicorn Some Handmade Plastic Molds have what may appear to be watermarks. This happens in the vacuum forming process. If you glaze your finished pieces with Resin, the watermarks will not show. I try hard to make the molds with little to no watermarks, but, from time to time they can be unavoidable.
