Just that
Care to share?
Yep. Carry one in my pocket every day. When the cashier says that will be $7.46, I give them seven dollars, and reach into the purse and pull out four dimes, a nickel, and a penny. Change I get back from the cashier goes in there, too.
I was sent to first grade with one of those containing my milk money. They haven't changed in all those years. Same design and material.
