I might try it to see how it is. On my hand though I definitely wasn't a fan. Perhaps fingers crossed it could work on the lips.
I'd hope for as close to retail as possible, but obviously as it'll have been swatched on hand and possibly lips (I'd clean it with rubbing alcohol before selling to sanitize) I probably can't really ask for that. However if you're interested I'll PM you once I've tried it on my lips if I dislike it and we can work something out?
No probs, pm if you decide you don't like it :)
