My DD bought herself a nails kit (when I told her not to, they looked bloody awful, not a bit like the salon ones she had in the Summer. That's why, dear DD , you go to a salon to have them done not try and stick them on yourself. Its difficult enough painting with your weaker hand let alone doing acrylics)
As I didn't want her to knacker her nails though- acetone remover (I have the Sensationails stuff) warm in a pyrex bowl over hot water - it bubbles and stinks. Soak, cotton pads, foil wrap , leave 15 minutes and they should soften enough to nudge with a wooden nail stick.
