I'm not sure what's more exciting about these lip gloss kits: that all the ingredients are 100% natural (no additives, dyes, synthetics or fillers), or that you get to make lip gloss that resembles a mini lava lamp! No matter how many times you flip the lip gloss bottle upside down, the groovy lava lamp colors are "bubbly"-but they do not mix together. The gloss rolls on smoothly, giving your lips a healthy shine, and the essential oils give them a yummy scent. Kits include easy instructions, safflower oil, castor oil, various colored glycerines, 2 scented essential oils and roll-on lip gloss containers. Adult supervision may be required for the younger children.
