This 5-1 bit is our flagship bread and butter. Constantly out of stock and for good reason. This is a sharp end bit perfect for sealing the cuticles. Sealing of the cuticle area allows longer retention and also a flush aesthetically pleasing cuticle area. This bit and like all NDS Beauty pro bits are designed to last longer and the more seasons the bits the better they perform. This is the ultimate finisher bit for any nail tech looking to do flawless cuticle work and is great for smoothing and finishing sets.
