Whats Up Nails - Pure Color #13 Gel Flat Brush for Nail Art, DIY Manicure & Professional Salon Use | High-Quality Nail Painting Tool for Smooth Gel Polish Application

I wasn't sure if I needed the entire set of detail, liner, and striping brushes when I bought the Whats Up Nails Pure Color Brushes 3-pack, but I'm very glad that I did. I'm using all three brushes. The detail brush has proven indispensible for drag marble and touching up mistakes. The striping brush is a one-trick pony, but necessary for striping on long nails. The liner brush offers more control than the striping brush on short nails and can pull more polish than the detail brush. It's an in-between brush that works for tasks where the other brushes are cutting it.I am using these brushes for polish, not gels or acrylic paints, so I was concerned that frequent cleaning with acetone might damage the natural sable bristles. So far, the brushes are in good shape. I clean by swirling the brush in acetone, then wiping it off. I dab a little of my rinse-off hair mask that contains both oils and keratin onto the brush and massage it into the bristles. I leave that for a while, then rinse off and allow the brush to dry. This is how I treat my natural-fiber makeup brushes and it works beautifully. It might be overkill for nail art brushes, but I want these to remain in good shape.Each brush comes individually packaged with a cap and a small packet of rubber rings that you can use to replace the black, rubber grips on the brush handle. I find that those grips really do help me control the brush. The handles and caps are aluminum and have the brush number (9, 10, or 12) painted on the side. Like all nail art and gel brushes, they are quite long when the cap is attached: 7.25 inches (18.5cm). The brushes without the caps vary in size due to different brush lengths, but if I exclude the brush, itself, each handle, including ferrule, is 6.5 inches (14cm) long.I also have the Whats Up Nails Watermarbling Tool (7). It's more precise than a toothpick for watermarble, but I use it primarily for drag marble. I prefer to use the detail brush to drag thicker polishes, as there is less risk of cutting through all layers of polish, then having the polish refuse to close up behind the drag, as the polish is too thick or is drying too quickly. With the brush, I can more easily drag just the surface, which is helpful when working with polishes not ideally suited to drag marble. The marbling tool is perfect for fine drag flourishes in polishes of medium consistency.
