How to use

Open the label printer cover on a compatible Brother M-series or P-touch device and insert the cartridge following the printer's alignment guides until it clicks into place.

Usage recommendations

For best results, store unused cartridges in a cool, dry place away from direct sunlight. Use the 9 mm width for short lines of text or small icons and select a font size that ensures characters remain legible. Avoid prolonged exposure to moisture or abrasive cleaning solvents on applied labels to preserve legibility.
