Magic Nails - set of 72 nail stickers for kids. How does it work? Easy: stick on nails for a safe, fun and creative manicure. The stickers can stay put for 1 or 2 days, provided they’ve been applied evenly on clean nails. They resist a good hands wash but not a bath. Please remove them so they won’t disappear with the water (not planet friendly). After use, dispose the stickers in a recycling bin. They also enjoy a second life in a notebook.
