Square Cup Silicone Mould (86mm x 66mm)
This square cup silicone mould is designed for casting small containers, holders, and decorative resin pieces with clean edges and smooth internal surfaces. Made from flexible silicone, it allows easy demoulding while keeping its shape over repeated uses, making it a practical choice for both test pours and finished projects.
The mould features an approximate top opening of 8.6cm and a height of around 6.6cm, giving you a compact but versatile cup format suitable for epoxy resin, polyurethane resin, plaster, or similar casting materials. Its sturdy walls help maintain consistent shape during curing, while the flexible body makes removing cured pieces simple without damaging fine details.

- Approximate height: 6.6cm
