Super-fine, Extra-fine and Fine detailing brushes (B01).

These sable brushes are 5.5 inches (130 MM) long and fit comfortably in your hand with a nice feel and balance.

The cone-shaped handles taper to a fine point that allows for better control while to raised logo label prevents slipping.
They can be used with acrylic or oil based paints.
