This is one of our small plastic hobby plaster moulds. These moulds6 are durable and with care will produce many castings. We recommend you rinse the mould with Aldax CraftRinse to wet the surface of the mould, allowing the plaster to flow smoothly into all details of the mould without trapping air bubbles. Aldax CraftRinse is available from the mould making supplies category
