Tip Blender softens the plastic to allow the technician to blend the tips quicker and decrease the trauma to the natural nail. "Tip Blender" can also be used to keep the brush clean in the "Brush-It Activator". Applied to the seam area of the nail tip, the Tip Blender will melt down the tip, making it faster and easier to blend your nail tips. It is also perfect for brush cleaning and is harmless if it comes in contact with the skin. Available in 1/2oz and 4oz
