Once you have some Lista cabinets it is easy to make nice labels for the drawers. I use Excel to make a spreadsheet of what I want the labels to look like, print them out, cut them to size (I use a large paper cutter but scissors or a razor knife will work) then slide them into the handle. I usually use colored paper to visually separate the drawers by what they contain (nuts, bolts, size, metric or standard thread, etc.).
Lista labels usually are about 1" tall and about 25 1/2" wide (3 times the width of a sheet of paper). My Excel spreadsheet is set up so that the row size is the same as the height required for the label. 3 rows on the printout sheet gives me a label for one drawer. To get started format the row height @ 64 and the font @ 48 set to BOLD, you may have to adjust the row height as needed.
To remove the end cap on the handle, press the square button inside of the drawer while sliding the cap out of the end of the handle. Insert the label behind the clear plastic and replace the end cap.
