These are Nail Decals not Nail Stickers.
Nail Stickers & Nail Decals do the same thing except the instructions are different.
Nail Decals Instructions:
Nail Decals are more fragile than Nail Stickers but are a great affordable option to get the same results as Nail Stickers. And you can definitely make them work just as good as Nail stickers. Simply make sure you seal them in with a generous layer of top coat and don't forget to seal in the free edge to make sure the decal is nice and protected.This product has no specific sizes
