This is the second mold I have bought from The Bath Time and all I can saw is wow. Their products are awesome and their costumer service is unmatched. I highly recommend!
I have a bath bomb press and finally got a recipe that I can actually make bombs. I was nervous that it being steel was part of my bath bombs working out. However, I tested it with these molds and they turned out just as great! So glad I can have fun molds without having to pay an arm and leg on my press molds!
