The Mini Sumi brush is shown at the bottom of the photo. The photo shows the comparison of the 4 sizes available.
Soft Black Natural Hair Sumi brushes. Great for sumi shading that Paula McCoy does on most of her ceramic projects “Class in a Bags” and great to shade on glass enamels with color concentrates or glass enamels.
We do sell a 4 piece set that includes all four sizes which are sold separately.
