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.
