Another week, another nail polish to test. This time it's 17's Supreme Shine Nail Polish in Coral Pop, £3.99 (Boots), a colour made for beach-bound toes and picnic-eating fingers. In a word, it's summery. The polish boasts a glossy finish and colour that apparently lasts up to 10 days. Now I always find this rather a vague statement. Of course, if I left my nails for 10 days, some, in fact I'm sure most of the colour would still be present 10 days later, that is if you don't mind large, gaping chips at the tips of your nails. If however, they do mean 10 days-worth of chip-free colour then I'm afraid I can't quite attest to this.
