The zippered compartment on the back is long enough for three stacks of bills placed end-to-end. This is a discreet way to carry hoards of fifties or hundreds on long trips...or just a safe place to forget a single ‘emergency’ dollar. A flat row of quarters will fit, too. One size fits all. Belt can be shortened by cutting and fusing. Black nylon webbing 1.25" wide, 46" long. Durable cam-action black nylon buckle (money not included).
