Golden Rose Black Diamond Hardener

A strengthening nail treatment enriched with diamond powder and vitamins to protect and fortify weak, brittle, or soft nails. The formula acts as a durable hardening shield, preventing breakage and splitting while promoting healthy growth. It provides a glossy finish that can be worn alone or under polish as a base coat. This fast-drying, non-yellowing hardener also helps smooth nail surfaces and enhances overall nail appearance. Ideal for anyone seeking visibly stronger, healthier nails with a beautiful natural shine.
