This is a great set for bath bomb molds and cute things to include in them. The molds work well. Just be aware this isn't a complete starter set. You still have to purchase the basic ingredients for the bath bombs you want to make. There are "recipes" all over the internet and you can choose which one you want to use. Some basic ingredients tend to be citric acid, epsom salt, and baking soda. Of course, each recipe varies.
This set is for when you have your recipe and are ready to make your bath bombs.
Having used "hacks," such as clear Christmas ornaments which come in halves, to make the forms I am thrilled to see an easy form which won't crack or be impossible to unmold at such a reasonable price.
