Can also be used for pedicures! All sets are new, fully sealed, and come in their original cardboard packaging. Each set is individually wrapped in a clear, plastic sleeve. All sets are stored in plastic storage containers in a temperature controlled home. Our home is smoke free, but pet friendly. All nail sets are temperature sensitive because they are real nail polish in a strip form. So, do not leave out in the sun or in places of extreme heat or cold. If the nail polish strip appears dried out or inflexible, warm the strips up before use to make the nail polish pliable again.
