A currency strap is a simple paper device designed to hold a specific denomination and number of banknotes. For Danbooru's purposes, this tag refers to the orderly bundle of Banknotes itself. These are commonly seen carried en masse in a Briefcase and can be seen in illicit business dealings and the like, as well as in ordinary transactions at Banks (often in the Bank Vaults themselves) and financial institutions.
