Quoted from The National Parenting Center:
The Mini Cosmo Nail Polish set is an excellent activity for little ones who love all things fancy! These polishes thrilled our child testers because they are wonderfully colorful and just their size. On the parental side of the equation, they love the polishes are non-toxic and they do not have a strong nail polish scent, which was a real relief for testers. The polishes are indeed “mini” as is the included nail file and nail decals; this helped in painting small kid nails and even the parents nails (yes, Moms and Dads had their nails painted all the time!). Once dried, the polish peels off of skin and even nails (if things get a little messy in the “salon”). Parents appreciated that nail polish remover was not necessary because the colors peel off easily. This lets children can change their nail color easily and often. The packaging is minimal and the display nicely shows all the colors included in the set. Parents felt that this could be a great stocking stuffer.
