These durable, long-lasting press on nails are lightweight, customizable, non-toxic, and non-damaging. How To Apply: Start with clean, dry hands. Using number guide on backside of nails, fit each nail to the right shape. Apply glue to the entire base of your natural nail, then press and hold the Mani Muse nail for 15 seconds till glue activates. How To Remove: For best results, wait to remove nails till they are naturally lifting (never force or pull nails off). For a water based removal, soak nails in warm soapy water for 10 minutes. Using a cuticle stick, lightly push under sides of the nail to lift off. Gently buff off any excess glue. For an acetone based removal, gently file the top layer of the Mani Muse nail. Place an acetone-soaked cotton ball over nail and wrap with foil. After 15 minutes remove any excess product with cuticle stick.
