Electronic labeling system

This Brother P-Touch label maker was a total lifesaver when we were organizing the office, although you might want to keep it hidden from curious five-year-olds who can burn through an entire spool of tape in under three minutes by printing things like POOP or BUTTTTT. We labeled folders, drawers, shelves, boxes, and eventually slapped labels on each other’s foreheads. Great price for something you’ll use all the time.
