Bought this to entertain 4 girls ages7-8 at a sleepover. Within seconds they were crowding around me at the table waiting in turn for their nails to be done - I wouldn't recommend letting them loose on their own.
The varnish is very glittery but pale, and eager girls wanted to stick the jewels on before it dried, so the jewels didnt stay on long. The nail strips were really a waste of time, fiddly to do and off very quickly when washing hands, they are not that sticky. You need sharp little scissors to cut the strips. Find something else to decorate with those.
The girls soon lined up again though for their tattoos, these are lovely, so many to chose from. For about £1 each, 4 girls were all glammed up for their sleepover and while they were busy with their nails, they were not running riot around my house!
