"CosmoTop Spin, Set of 4 - This 4 brush-set contains two Series 5580 Round sizes 0 and 6, one Series 5880 bright size 10, and one Series 5584 Oval size 8. Da Vinci Cosmotop Spin Brushes hold more water than any other synthetic, with a large belly that tapers to a fine point. The blending and placement of five different diameters of fine synthetic filaments make this brush perform like natural hair. The long-lasting, high quality synthetic fiber in these brushes has an energetic spring. Every brush is made by hand, so the handles may vary slightly in appearance." -Blick
