A square coaster mould made from flexible silicone so it's extremely easy to demould and can be reused multiple times.
The dimensions of the cast coaster are approximately 10cm x 10cm x 0.7cm deep.
If you need an opaque coaster mould for easy spotting and release of bubbles, or if you need a firmer mould, we recommend getting our handmade square coaster mould instead.
Moulds with slight defects are still suitable for Jesmonite casting as the defects will not be visible. Slight defects may include tiny dents, slight scratches and matt patches.
