Set of 3 Vanity Clothes Lint Brushes Celluloid Pyralin Vintage Art Deco

Lot of 3 vintage vanity brushes. Not sure of their originally intended purpose -- possibly for clothing lint? They are some kind of early plastic (perhaps celluloid or Pyralin) with a darker brown rim. Two are a matched pair measuring about 5 long and 2 wide. The third is the same style and material, but a different shape (about 6 long, 1.5 wide). They are in good shape with some surface wear from handling. No chips or cracks in the plastic. Location: B
