Very easy to use 10 molds, perfumes 2, 3 colors (can be mixed to more color) My 3 year old daughter and 10 months enjoyed and made the molds 10 in the same day (the day we received the package) The soap (glycerin) is heated in the microwave very quickly, just put a few drops of perfume using pipettes included in the box and then it add some drops of coloring and finally pour into (or molds) and allow to cool and harden for 30-40 minutes.
