6+ large, about 10.75 x 14”
6+ small, about 8.5 x 11”
These are the protective trays that cases of pet food come packed in, like shallow boxes but without lids. The large trays are great for sorting and organizing papers. The small ones are just slightly too narrow for 8.5”x11” papers to lay completely flat in, so not ideal for storing papers, but they are still good for sorting, and as makeshift pull-out drawers in 12”-depth cabinets (not pretty, but very functional!)
