Material: these moulds are made of quality soft silicon which are translucent so that you can clearly view the inside of these moulds, easier for you to operate
Multi-function design: these resin casting moulds work as multi-functional tools which are convenient for making DIY projects, earring pendants, necklaces and beautiful jewelry pieces or just making some accessories for your handicrafts
Easy to use: the resin moulds have smooth and soft surface, which allow you to put things and out easily, also have a long service life
Only one observation - the mould has no supporting structure ( unlike the round moulds ) and so they do not easily sit flat an a surface unless a lot of tac spray is used. Even then there is a tendency to warp.
