If you have always wanted to try to make bath bombs but not sure what molds to get, I recommend these. This kit comes with 12 molds, 4 ropes in case you anted to hang some and a measuring spoon. A great thing about the spoon is that a full spoon is 1oz great for easy measuring. The molds are plastic and very simple to use and to clean. I’ve never made these before but I enjoyed trying these out. They make perfect bombs every time. Looking for something to do with your kids, try making bath bombs, they are fun and easy. You can use any essential oils you want and you can even use coloring. Each mold makes the perfect size and each hold 3.8oz. I received this product at a discount for my honest opinion.
