Step 1: 
Gently rub the polish on your nail surface.
Step 2: 
Open the cover, take out the plastic cup, and add nail polish remover/ acetone (about 5ML). Put the cup, close it, and tighten the sealing cap.

Connect the plug and turn the power on. When the indicator light turns to S (approximately 2 minutes after power on), put your hands in and start steaming your nails.
Step 4: 
Take your nails out around 10 minutes later and use a peeling spatula to remove the nail polish. Done!
