Okay, I posted on this.....but for some reason it never showed up. So sorry if this is posted twice!
I am addicted to Chapstick's Glitter Lip Balm. It smells like tropical fruit and has this wonderful shimmery look to it. Which looks great under lipstick or alone. Added bonus is that it is super cheap! So you can bulk up on it.
They also have a Lip Gloss balm, but I haven't tried it yet.
