With the Rico Design Silicone Soap Matrix, it's easy to customize your handmade soaps. The matrix will allow you to apply clear and deep prints in your soaps. The mold is flexible while remaining stable and supports heat. To use it, simply put the soap matrix in the bottom of a soap mold (pattern up), pour over the melted soap. Once the soap is dry it is easy to remove the matrix by the side. Then clean the matrix under clear water. All soap matrices are reusable. Dimensions: 5 x 5 x 0.5 cm.
