Irish Lass, I think you will find them to be quite long lasting - I am not a Color Street consultant, just a huge fan. When I was wearing them religiously I would change them every two weeks out of boredom rather than necessity. I have to get back to wearing them again (I got lazy and forgetful, it just hasn't occurred to me to do it while I'm watching TV, usually 5 minutes before I fall asleep my brain will remind me that I haven't done my nails in forever...) The only reason I stopped wearing them was because I was working on stripping a piece of furniture, and it would never fail that my gloves would break and the stripper would dissolve my nail polish.
