The silicone moulds from this manufacturer are "not" made of food-safe materials. For this reason, we would like to point out that they should not be used for baking, making soap or anything that could be eaten. In the field of furniture, decoration and DIY projects, there are no limits to the creative minds. As with all our other silicone moulds, you can easily use them with air-drying clay, casting resins (resin) or similar products. What we makes it even more special is our flexible paste, which are only injected into the moulds and can be removed after 24 hours (depending on the size of the mould) and - they remain permanently flexible.
