Type 7 – Cardboard Tube
1926 – 1945?
The Type 7 can is made completely out of cardboard including the top and bottom. A paper label identifying the balls covers the can. This type was made around the time of World War II when there was a shortage of metal. A string was used to tear the paper label from around the top for opening, much like the metal key wind strip found on metal cans of the period.
