I use these to assist my employees in locating our oldest stock items so that we keep in proper rotation. Besides being colorful, I print "USE FIRST" on each label. This ensures my employees pull the items I would like used. They are easy to print and peel and they stay on cardboard boxes without falling off. It would be nice to have these in 8 1/2 x 11" sheets so that I didn't have to load them into the single sheet feed of my printer.
