- DO NOT rub, otherwise you risk ruining the product or its embossed surface.
Do not test polymer clay products for strength, durability and flexibility. Of course, polymer products are quite elastic, so they will not be damaged if dropped from an insignificant height. But if you start checking such a product for strength, picking, scratching with sharp objects, throwing, then it may lose its integrity forever.
Polymer clay is not compatible with solvent, perfumery, alcohol, acetone, as well as other chemical compounds that can subsequently cause significant and irreparable harm to its surface.
