i have so many bottles of opi, and i was just wondering how long they last? have you ever had an opi nail polish that expired? how long did it take? :O (i have the new 3-free ones, which might not last as well as the old ones :S)

and i don't really care about bacteria, i couldn't imagine anything wanting to live in such chemical smelling goop :S

i have my hopes up, cause i found an old revlon nail polish that i bought 3-4 years ago and it's still perfect (: not gloopy or funny smelling at all (:
andd if you have any tips to make it last longer, i'd love to hear them (:
