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. ___________________________________________________________________________ Disclaimer: Some sets might have stylist sticker, writing or back perforation lift but all are factory sealed. I cannot guarantee the application of older strips so please buy at your own risk. I have never had issues with older strips.
