The Squeeze and Flo bottle brush is perfect to be used with Mehron Mixing Liquid and Mehron Metallic Powders or Precious Gem Powders. Combine the powder and liquid before your gig and paint like wild without making a mess! This set comes with 4 different size brushes: 1/4" Flat, 1/2" Flat, 3/4" Flat and 1" Flat. The large brush can cover a lot of skin very fast, which makes it great for body painting. The smaller sizes are great for more detailed areas.
