Comes with 2pcs in a protective plastic jar!
How to apply: Option 1: Apply a small bead of clear acrylic to the back of the charm where the spinning mechanism is, then press onto the nail and let it dry.
Option 2: Put builder gel on the same place I referenced before, push onto the nail, and cure for 60 seconds. Make sure to put enough gel. The gel should slightly seep around the spinning mechanism to secure it. The excess gel will not be seen.
