Start by soaking a little bit of the cotton wool in nail polish remover, don’t add too much as this will make a mess instead do just a small section big enough to cover your nail.
Place it over your nail a press it down, cut a piece of tin foil and wrap the top of your fingers still with the cotton wool inside. The point of the cotton wool is simply to hold the cotton wool in place.
Squeeze the tin foil tight and leave to soak for 3-5 minutes.
When removing hold the tip of the tin foil which is on top of your nail, squeeze tightly, wiggle and pull off.
You will them be left with perfect nails with no glitter and no nail polish.
This technique is much faster in the long run and far less stressful then having to watch your cotton wool pad get stuck to the glitter on your nails.
