You guys are too funny!
These were actually used as pocket warmers. Here is a quote from wiki...

Charcoal hand-warmers provide heat through the burning of charcoal in a special case. These can last up to 6 hours and become comfortably hot. The cases for these usually have felt on the outside and have materials inside that do not burn, but spread the heat evenly such as metal. To activate, one or both ends of a stick of charcoal are lit and then quickly extinguished to create a hot ember. The smouldering stick is then placed inside the case and the case is tightly shut. The charcoal sticks are available from most outdoor activity shops and are fairly inexpensive.

Early 20th century and used widely by world war I.
