Trapper Keeper is a brand of loose-leaf binder created by Mead. Popular with students in the United States and parts of Latin America from the 1970s to the 1990s, it featured sliding plastic rings (instead of standard snap-closed metal binder rings), folders, and pockets to keep schoolwork and papers, and a wrap-around flap with a Velcro closure (originally a metal snap closure).
Trapper Keepers usually had a theme, such as a cartoon, television show, or video game. Between 1988 and 1995, "Designer Series" Trapper Keepers featured abstract designs and, later, computer-generated images.
