Supplies Stainless Steel Ball Mould - 55mm

As described

Essential for making your bath bombs

Difficult to unmold and expensive! The silicone one works better

Impeccable My first bath bomb is superb! I made the Orange Blossom recipe, it smells like summer, a delight!

bath bomb mold I bought these stainless steel balls to make bath bombs with my children. After reading the advice in the various reviews I put the molds in the freezer after making them, I am disappointed because the balls still did not hold once unmolded and in the open air... Any advice so that they hold and do not crumble? Thank you
