Silicone Mould

Square Storage Box Silicone Mould

This silicone mould is designed for casting a square storage box with a matching lid. While the mould includes internal support sections to aid casting, these are not visible in the finished cast, resulting in a clean, uninterrupted interior.

Manufactured from flexible, durable silicone, the mould allows the box body and lid to demould cleanly while maintaining straight edges and consistent wall thickness. The simple square form makes it suitable for decorative storage, trinket boxes or small organisers depending on the casting material and finish used.

For best results, ensure the mould is placed on a level surface during casting and allow the material to fully cure before demoulding. A suitable release agent may be used depending on the casting material.
