antique french ivory celluloid vintage vanity box, natural bristle brushes

Lot of lovely old vanity table brushes and a hair receiver box (we think? it's about 4 1/2" in diameter, with a hole in the center of the lid). The brushes are natural bristle, one a hairbrush, and the other a clothes brush?

All are ivory celluloid, without chips or cracking, but having some discolored areas from age and use. The brush bristles are nice and thick, but have a little bending from years of storage wrapped up in a box.
