To find the correct size for your nail, just check the wrap against your finger and choose the one that is just smaller than your nail. Avoid overlapping the wraps onto your skin or cuticles as this may cause lifting at the edges. Cut the nail wrap in half before filing the excess away to make two uses out of every wrap. If the nail wrap does not fit your nails, you can cut the next size larger and trim the nail wrap down to fit your nail. Apply a top coat (NOT fast drying) to the nail wraps for a shinier look and longer lasting nail wraps (Cap your tips to make your wraps seal with your nail even better).
