I was a little intrigued by the new Impress press-on manicure line though. They've had quite a lot of attention since their launch, especially since they've got Nicole Scherzinger on board for their advertising campaign.
I'd estimate max wear time for these would be about a week, with a few replacements here and there. I decided to take mine off after 4 1/2 days. Surprisingly, not one fell off of it's own accord. Even if it did, they give you lots of spares so if you lose one you can simply pop another on!
When it came to taking them off (the part I was dreading!) they were actually a dream to remove. I didn't even have to soak them in nail polish for a few seconds as the packet suggested. I simply peeled them off. They didn't appear to leave my natural nails damaged in the slightest (especially when compare to glue-on falsies!)
They aren't cheap at £7.99 for the plain designs and £8.99 for the patterns, but they are certainly fun for a holiday treat, or if you are short on time. I will definitely be trying these again. You can pick them up in Boots, or online here.
