4 Piece Skull Mold Set – Flat-Back Skull & Bone Casting Molds by Pacific Mold Design

One of Pacific Mold Design's most popular mold sets, this skull mold bundle lets you cast multiple realistic skulls and bones with store-bought cement or plaster. Designed for efficiency and reuse, this set allows you to produce detailed castings at a low cost per piece—ideal for décor builds, haunted attractions, and creative installations.

Each mold is made from durable ABS plastic for long-term use and consistent results. With proper care, you can complete multiple pours while maintaining crisp detail. For best performance, apply a mold release (such as cooking spray) before each pour to ensure smooth releases and preserve the mold surface.

Resin, foam, and other high-heat casting materials are not recommended.
