This is a total of 4-pack of square coaster molds used for resin casting.
High-quality 100 % silicone and super easy to de-mold your creations. Designed for the resin artist in mind. The mold is used to create any geode inspired coaster, perfect for holding hot and cold beverages. These molds are deep to allow for a range of depths in creation based on personal preference.
Each mold is shiny and perfect for creating an approximate coaster size of 4-inch diameter and a beautiful natural looking stack of coasters.
Use up to 4 oz of resin in each mold depending on the depth desired. Be sure to wash with warm soapy water between use.
