Triangle Spike Pendant Silicone Mould (Multi Cavity)
This triangle spike pendant silicone mould is designed for casting multiple elongated pendant shapes in a single pour, making it easy to produce coordinated jewellery sets, charms or decorative resin pieces. Each cavity includes a pre-formed hanging hole, so your finished casts are ready for findings straight out of the mould.
The mix of slim spike shapes and smaller accent triangles works especially well for colour layering, marbling, transparent pours or bold solid finishes. It is a great option for batch production when you want consistent results without swapping moulds between pours.
- Multiple long triangle pendant cavities in varied sizes
- Built-in hanging holes on every shape
- Flexible reusable silicone mould
- Suitable for epoxy resin, Jesmonite and plaster
- Ideal for jewellery, charms, keyrings and craft projects
Approx dimensions:
Overall mould size: 108mm × 81mm
Mould thickness: 5mm
Longest pendant cavity approx 51mm tall, smaller cavities down to approx 25mm
Allow resin to fully cure before demoulding. Clean gently after use and store flat to help maintain crisp edges and consistent shape over time.
