I love glitter nail polish, In fact I own about 50 of them, but I hardly ever wear them because they are such a pain to remove. When I visited Paris this year, I took the opportunity to visit Sephora and picked up Sephora Instant Nail Polish Remover For Glitter. Its just like a normal nail polish remover pot except for one thing. This product has an abrasive strip (Sephora calls it a scrubbing sponge) about a centimetre wide inside the pot. You can use this product to remove normal polish which it does in a flash, but if you are trying to remove glitter polish then you just rub your nail on the abrasive strip and in about 10 seconds all you are left with is a few dots of glitter which you can scrape off yourself. Its so much faster and easier than the foil method I find. The abrasive strip is not so harsh that it damages your nails, but just enough so it makes light work of the glitter.
Its $9.50 on the US Site here and its €8.95 on the French Sephora site here. Sadly its not available to ship to the UK, so I would advise you to stock up next time you happen upon a Sephora when you are on holiday. Why oh why do we not have a Sephora in the UK. I posted about my Sephora Haul here.
I bought this product with my own money
