Rectangle Agate Tray Mould

Molds are made of good quality silicone material, flexible, thick, washable and reusable
They are easy to use as their smooth surface makes it easy to cast and de-mould it, after ensuring that resin has completely turned solid.
You only need to twist the silicone mould to release your creation from the coaster mould.
