I'm not even sure where I heard about this company, but I first looked into
Rainbow Honey because they were doing a nail polish collection based on My Little Pony: Friendship is Magic, which I love. The Equestria collection has 8 polishes that come in 15ml and 7ml options. I chose to get the 7ml ones, partly because I have never made it through a full-sized nail polish and partly because they were cheaper. I got all 8 for $35. The 15ml set is $70. Shipping was a little slow. It took about 2 weeks to get them.
