"Gives a smoother shave with any electric shaver.
Rub lightly over your face before shaving to dry up perspiration
and facial oils. Sets up your beard for a close, comfortable shave.
Also refreshing for after shave use. Non-abrasive. Will not harm
shaver heads." -- Parks Advertisement

sqeezed from a tube and whipped up into a later in a bowl. The cream
was applied to the face with a bushy brush, usually made of badger
hair.
