Our line of premium nail tools will not disappoint! This Liner Brush will certainly boost your nail tool arsenal. The brushes work incredibly well with gels, acrylic paints, and polishes, but are Not recommended for acrylic powder use. The brush comes with a protective cap to keep your bristles safe and your points pointy! The see-through, crystal-filled handles add a touch of flare, but if you want to keep those crystals popping, do not use acetone to clean the clear plastic handles. They will become cloudy since the plastic is not acetone resistant. For the bristles though, acetone is okay to use on the brush only if using nail polish.
