Small craft coffin molds are made from silicone — a soft, elastic, reusable material that releases cured resin or soap easily. The life-size decorative coffin is made from screen-printed nylon stretched over a flexible metal (spring) frame with PVC support tubes for stability.

Small craft molds are shown in two common sizes: about 12.5 × 7.5 cm (≈4.9 × 3.0 in) and about 8 × 6.4 × 1.1 cm (≈3.1 × 2.5 × 0.4 in) for quicksand-style molds. The assembled life-size coffin measures approximately 60 × 24 × 10 inches (listed in some product text as 10 × 24 × 60 in overall).

Fill the silicone mold with your chosen casting medium (epoxy or casting resin, wax, or soap), add any mix-ins (glitter, beads, dried flowers, etc.), pour and allow the resin to fully cure, then twist and push the cured piece out of the flexible mold. The silicone’s smooth surface makes demolding easy and supports small items like pendants and keyrings.

Common mix-ins include glitter, sequins, pearls, beads, confetti, dried flowers, seashells, and floating accents. Colorants such as pearl pigment or mica powder are also used. For quicksand or waterfall-style effects the product text mentions quicksand oil or water-based blends (e.g., water or water–glue mixes) depending on the specific kit or project.

The molds are made of flexible silicone that’s described as durable, elastic, and reusable. Their smooth surface makes demolding easy, and product text indicates they’re designed for repeated use rather than being fragile.
