Nail forms are a constructed adhesive application that are used as a temporary base to apply artificial nail extensions and enhancements without the use of a artificial nail tip. These are called sculpted nails. Nail forms are temporarily placed under the natural nail while you apply the nail enhancement. Nail forms are removed once you are finished applying/curing the nail extension. Nail forms can be used for acrylic nails, polygel, builder gel nails and more! 100pcs should last for 10 sets of nails.
