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.

  • Square jar design
  • Includes segmented internal insert
  • Reusable flexible silicone
  • Suitable for resin, Jesmonite and plaster
  • Ideal for decorative or functional storage

Approx dimensions:
Jar width: 76mm
Jar depth: 77mm
Jar height: 48mm
Insert width: 64mm
Insert depth: 64mm
Insert height: 18mm

Allow casts to fully cure before removing from the mould. Wash with warm soapy water after use and store flat to maintain shape and detail.
