Cover Girl wetslicks AmazeMint lip gloss. I am LOVING this stuff.
I'm not sure I've found the right shade yet, but the "mint" part is so great. I'm not sure that it's terribly long-wearing, either, but it's lip gloss, and I've never found any lip gloss to be particularly long-wearing.
In any case, for $5 (less if you have a CG coupon from the newspaper or online), it's definitely worth a try.
