Good, clean fun! Pun intended. It came with enough supplies for many, many soap molds. We had so much fun with this easy, yet visually satisfying project, that we ran out and bought more materials from a hobby store so that we could make more and more and more. A great gift.

I got this kit for my 7 yr old. He and my 9 yr old did it together and had the best time creating their soaps. We made 3 and have enough supplies left over to make more another day.

Got this soap making kit for four of my grandchildren ages 4 years old to 8 years old. Although the younger ones needed a bit of supervision, they all thoroughly enjoyed the experience of making the soap and ended up with a variety of colors and shapes. The hardest part according to their mother was waiting to use the mold!
