To use this DND Dap dip powder, first prep your nails as usual. Then, dip your nails into the powder after applying a base coat or monomer liquid. You can repeat the dipping process to get your desired thickness. Once you're satisfied, seal it with a top - coat. Make sure to work in a well - ventilated area when using the monomer liquid. For maintenance, avoid using your nails as tools to prevent chipping. Also, keep the powder in a cool, dry place to maintain its quality.
