A delighfully well used pair of round French copper collared natural bristle paint brushes. These older well patinated brushes are so hard to find these days!
 
They measure 12" and 14" long. The longer has some old worm holes, now empty, I have treated it to be sure.  The 12" brush has some turquoise and grey paint with a yellow ochre tip. The copper collars have developed a deep patina of age.
