Thick silicone keeps box edges straight during deep pours. Cast in two shallow stages or support the outer mold to avoid wall bulging.

Care

Follow your resin maker mix ratio, pour-depth limit, and cure schedule. Demold only after the resin is fully cured. Wash the mold gently with warm soapy water, rinse, and dry completely before storage. Avoid sharp tools against the silicone surface.

Handmade molds may vary slightly in size and surface. The color and dimension of finished casts can vary with resin brand, pigment, and casting technique.
