Round Silicone Jar Mould with Lid Insert (100mm x 86mm)
This two-piece silicone mould set creates a smooth round resin jar complete with a recessed lid insert. The main mould forms the jar body while the separate insert produces a neat internal lip, allowing functional containers to be cast cleanly and consistently.
Made from flexible silicone for easy demoulding and crisp surface detail, this mould works well with epoxy resin, Jesmonite, plaster and similar casting materials. A good choice for storage jars, candle vessels, desk organisers or decorative resin pieces.
- Two-part mould with matching lid insert
- Classic round jar design
- Reusable flexible silicone construction
- Suitable for resin, Jesmonite and plaster
- Smooth internal finish for professional results
Approx dimensions:
Jar top diameter: 100mm
Inner opening: 57mm
Overall height: 86mm

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