Brother eyeglass and shrink tube label cartridges are on 5 ft continuous rolls in
medium (1/4″ ID) and large (3/8″ ID). They are black ink on white media. Slide the label onto the earpiece and heat to shrink with either a hair dryer or heat gun.
Drop a cartridge into either a PT-E500 or PT-E550 label printer, close the lid, turn on the printer and start typing on the keyboard and press print. Print one or multiple labels with ease.
