OPI Nail Envy Original Nail Strengthener (15ml)
This award-winning strengthener is ideal for nails that peel, split, or crack easily. Infused with hydrolyzed wheat protein and calcium, it promotes stronger, healthier nail growth.
Use it as a base coat or on its own—either way, the results speak for themselves. Regular use leads to visibly harder, more resilient nails in as little as two weeks.
