How to Use
1. Start with clean, prepped nails for proper adhesion. 2. Shake bottle well to mix pigments evenly and avoid streaks. 3. Start by painting the edge of your nail with color, then sweep a thin layer across the full nail. Let dry for 1-2 min. Repeat step for a second coat. 4. Finish with Nature Strong Vegan Top Coat: paint the edge first, then sweep a thin layer across the full nail and allow to dry. Pro tip: While a base coat isn't needed, you can apply Nature Strong Vegan Base Coat first to set the foundation for color. Apply the same way: edge first, then a thin layer across the nail. Let dry 1-2 min before color.
