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. Great for making jewelry too16 strips total in one set 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.
