Square Silicone Jar Mould with Lid Insert (93mm x 96mm)
This two-piece silicone mould set is designed for casting square resin jars complete with a recessed lid insert. The main mould forms the jar body while the separate insert creates a clean internal lip, allowing you to produce functional containers in a single pour.
Made from flexible silicone for easy release, this mould produces smooth walls and sharp edges, making it ideal for storage jars, desk organisers, candle holders or decorative resin vessels. Suitable for epoxy resin, Jesmonite, plaster and similar casting materials.
