Bourjois Magic Nail Polish Remover (Boots £4.99)
I showed this in my recent haul (link) as a repurchase. When this originally came out, I thought it was going to be a bit of a gimmick but as it turns out this has dramatically changed my nail polish life. Yes it may not take 1 second, but it is so much quicker than using standard nail polish remover and cotton pads.
Simply stick your finger in the hole (*sniggers*) twist a couple of times, and voila gone! I found my last one worked well for about 3/4 months until Nails Inc Piccadilly Circus ruined it, and it was going quite sticky. It also has a lovely berry scent which is much nicer than the average nail polish remover!
Have you tried this?
