Nail glitter powders are a type of nail art product that can be used to add a sparkly, glittery effect to nails. These powders are made from tiny particles of metallic or holographic glitter that can be applied to the nails using a brush. They can be used to create a variety of designs, from subtle glitter accents to bold, sparkling nails. They can be applied over regular or gel nail polish, and can be cured under UV or LED light. They are also long-lasting and come in a wide variety of colors, shapes, and sizes of glitter particles, so you can create different effects. Some glitter powders can be used as a standalone product and don't require any base coat, others need to be sealed to get a more lasting effect.
