NAIL ART/LARGE MARSHMALLOW SILICONE NAIL ART STAMPER - 4 CM HEAD - CLEAR

When your stamper first arrives in the mail, give it a wash with some soap and warm water to clean off any oils or residues left from the manufacturing process. Let it dry completely and then use some sticky masking tape to clean off any remaining lint or dust. 
Give it a try!  Make sure you use a simple design to begin with, and have a few practice tries on paper. If your stamper is picking up the image right away from the nail plate and transferring cleanly to the paper, it will work fine on your nails. 
In between stamps, clean off excess polish with the sticky tape, or in extreme cases of mess, a little acetone on a cotton bud or ball.  Using acetone to clean your stampers will eventually break down the silicon and will lead to needing a replacement.
