Cuccio Pro 2-In-1 Premium Cuticle & Duster 1pc Nail Brush A 2-in-1 nail brush usually combines two essential functions: Cuticle Care: The brush may feature soft bristles or a specific design for gently pushing back and cleaning cuticles. It might have an angled or pointed tip to help in precise cuticle work without causing damage to the nails or surrounding skin. Dust Removal: The other side of the brush may be designed for dusting and cleaning the nails and surrounding areas. It might have firmer bristles or a different texture to effectively remove dust, debris, or excess product from the nail surface. Premium Quality: The term premium suggests that the brush may be made from high-quality materials that are durable and long-lasting. The handle might be designed for comfortable grip and control during use. Single Piece Design: The 1pc in the description indicates that it is a single piece, likely referring to the fact that it's a one-piece brush without detachable components.
