Say good bye to chipping & smudging. The nail wraps are made of Polyurethane, so they don't chip or smudge like nail polish. The best part? NO DRY TIME! On average the nail wraps last 4-14 days on you finger nails and 2 months on your toe nails. It all depends on how well you apply them, and how rough you are on your hands. If you put a layer of clear gel over the wraps, they can last up to 2 weeks. To remove, simply lift off. No chemicals are needed. Every order comes with 1 free nail file & an illustrated how to guide. Additional nail files/guides are available. If you are buying multiple gifts for different people, please purchase additional files for each recipient. How many pairs per pack? 7 pairs How to Apply: 1. Wash your hands with soap & water. Push back cuticles. 2. Select proper size. 3. Apply from cuticle line and cover the entire nail surface. 4. Press down firmly from center & side to side. 5. Fold excess material and file with long strokes in a single direction using the white side of the file. 6. Finish with gray side of the file to smooth out nail edge. How to Remove: 1.
