Square Silicone Jar Mould with Segmented Insert (76mm x 77mm)
This square silicone mould set allows you to cast a compact resin jar complete with a matching segmented insert. The outer mould forms the jar body, while the internal insert creates divided sections, making it ideal for multi-colour pours or separating small items.
The flexible silicone construction ensures smooth surfaces and easy demoulding once fully cured. Suitable for epoxy resin, Jesmonite and similar casting materials, this mould is ideal for jewellery storage, small keepsake boxes, decorative desk containers or gift pieces.
