The soft, flexible silicone allows for easy demoulding while maintaining crisp edges and smooth surfaces. Suitable for epoxy resin, Jesmonite, plaster and similar casting materials, this mould is perfect for small functional containers or gift-style pieces.
- Square jar design with matching insert
- Reusable flexible silicone construction
- Suitable for resin, Jesmonite and plaster
- Insert creates a shallow internal tray
- Great for jewellery, storage or decorative projects
Approx dimensions:
Outer jar width: 80mm

Allow casts to fully cure before demoulding. Clean with warm soapy water after use and store flat to help preserve the mould shape.
