I vote birthstones, food, or OS-tans!
But birthstones, fuck yeah, because I really love Art Nouveau.

Wooow, I really want to try this. I'd want to find a way to flavor it as well, but as someone who is always putting on lip balm, this is really cool.
I've made lip balms tons of times before - it's pretty fun (but messy!). I can message you with some starter tips if you'd like :D
