A small shaving brush with a two-tone handle — cream-colored at both ends with a black central grip section. The handle is made of a hard plastic or early synthetic material (possibly Bakelite or celluloid). The light-colored bristles are densely packed and likely made of natural fibers such as boar hair or badger hair.
This brush would have been used to apply shaving soap or cream, creating a lather for wet shaving. Portable versions like this were common in military hygiene kits, where soldiers were expected to maintain a clean shave even in field conditions.
