DYMO label cartridges are loaded with labeling ribbon that have to be replaced when the DYMO label-maker runs out of labels. Even when you are using your label-maker for official, important, non-practical-joke labeling, however, it may feel like you are running out of ribbon quickly. This ribbon does not grow on trees, and often can be quite expensive at office stores and other retail outlets.
DYMO cartridges can be inexpensive as there are great deals to be found online. You can be sure to have plenty of ribbon on hand when you stock up on DYMO cartridges at discount prices, so long as you keep them from the hands of mischievous coworkers and subordinates. Keep your DYMO device under lock-and-key to ensure that your cartridges last as long as possible.
