I’m not very familiar with how these Wisconsin Power & Lights tokens were used. I am assuming they were used for as a bus token. Token size is close to a dime.
Other than the token, each necklace is made with new materials. The size of a Ball Chain necklace is 20 inches. The size of a Leather Necklace can be adjusted to as large as roughly 25 inches and down to 12 inches using the two-knot system.
