Color Street is a brand of 100% nail polish strips that apply with no heat and no special tools, and are dry-to-the-touch immediately. They can last up to two weeks and come off with regular nail polish remover.. non acetone is best. Some sets may have stickers, residue from stickers, small tears or writing. Efforts have been made to remove and cover these things and Most do not have these on them but need to disclose that they could have them. I cannot guarantee the application of older strips so please buy at your own risk. I have never had issues with older strips.
