Made with 100% pure Kolinsky hair, Galaxy brushes are hand-tailored with exact curvature for acrylic nail sculptureThe medium handle measures 4.5" to 5" with weight-balancing for easy and accurate control. Hair: Kolinsky Shape: Round Color Black Metal if youâre a beginner to acrylic nails here 7 step to clean the brush STEP 1 Use a paper towel and some monomer to gently wipe down your brush. Do not be too harsh or aggressive. You want to avoid fraying or damaging the brush bristles. STEP 2 Fill your dish with liquid monomer. STEP 3 Leave the bristles soaking in the monomer. Depending on how dirty your brush is, this could take up to a few hours. You want to give the monomer the chance to seep into any hardened, leftover product. If the bristles are completely hardened, then donât hold back â let it soak for up to 48 hours. Pro Tip: Keep the brush at an angle, so the bottom of the dish doesnât mess with the shape of the bristles. STEP 4 Remove your brush and gently rinse the bristles off with warm water. You may prefer to fill up a cup with warm water and swirl the bristles around inside the cup. Whatever you prefer, just remember to do it gently and not to scrape, pull, or scrub the bristles. STEP 5 Air dry the brush on a clean paper towel and rinse out your dish. STEP 6 Once your acrylic nail brush is dry, put some new liquid monomer into your dish and soak your brush for another hour or two. STEP 7 Remove your brush from the liquid and once again, leave the brush to air dry on the towel. Do not rinse the brush off this time around.
