Hair collected from combs and brushes was saved in small jars of celluloid, glass, wood, or porcelain, with a hole in the lid through which the tufts were pushed. The hair saved in this manner was gathered up and formed into the pads (rather repulsively known as "rats" ewwww!) that were tucked under elaborate hair styles of the period to add fullness, especially if one was unlucky enough to have thin hair. I have quite a few of these hair receivers in my collection and have to try very hard not to add more ....that is NOT and easy task because they can be so beautiful . but I can enjoy them in someone Else's shop.
