Square Silicone Jar Mould with Lid Insert (80mm x 88mm)
This two-piece silicone mould set creates a compact square resin jar complete with a recessed lid insert. The main mould forms the jar body, while the separate insert produces a clean internal lip, allowing functional containers to be cast in a single pour.
Made from flexible silicone for easy release and smooth surface results, this mould is well suited for epoxy resin, Jesmonite, plaster and similar casting materials. Ideal for creating storage jars, desk organisers, candle vessels or decorative resin pieces.
