These Ultra-Convenient currency bands eliminate the need for time-consuming moistening, sealing, wrapping, or folding because they’re pre-glued. To use, just bend the short side of a stack of money into a “U” and slide the band over. All bands are ABA color-coded where applicable. All bands are made from 50# Bleached (White) Kraft Paper and they are packaged 1,000 bands per shrink-wrapped bundle.
