I was very disappointed with this varnish as it is not perfect and it dose not stay only 24 hours if you lucky. Would not buy again and when I went back to BOOTS they wanted a receipt to take it back and get a refund what a joke on something that can only be bought from them. BAD NEWS. 

I got some no7 nail polish over 4 years ago. I used it a couple of times before packing it with the rest of my stuff when moving to the other side of the world. Over there I got pregnant and - other moms will know what it means: never had the time to use it again. Today, with my two-year-old blissfully napping and not too many toys to put away, for the first time in four years, I have been able to give myself a little manicure. I wasn't very hopeful when I opened my long forgotten nail drawer, fully expecting caked, dried colours in stuck shut bottles. Yet lo and behold, everything was still smooth and looking brilliant as new. I must say it's only the no7 polish which did so well.
So even though I had never written a review before and I'm not much of the consumerist type, I thought these guys deserved a good word. Well done for a good quality product that lasts as long as we need it too.

I experienced disappointing durability with No.7 Stay perfect nail polish - chipped after a couple of hours, certainly couldn't wear it for two days running. Poor value for money. Not had this problem previously with No. 7 nailpolishes.

I put it on my toes and it didnt chip. Just as long as you give it enough time to dry, and put a great top coat it should be fine.

Boots No.7 Stay perfect nail polish is less durable than some of the cheaper brands, and it literally came off and started chipping within an hour of applying.
