Nail decals are a fun and easy way to add some personality to your nails. They come in a variety of designs and can be made from different materials, but most commonly they are made from paper.
Paper nail decals are usually made from thin, flexible sheets of PVC or Mylar. The sheet is printed with the design, then cut out and applied to the nail. They are easy to apply and remove, but not as durable as other types of decals.
If you're looking for something a little more permanent, you can try water-slide decals. These are made from thicker sheets of material, and the design is transferred onto the nail using water. These decals are more durable than paper ones, but can be more difficult to apply correctly.
