What the tape is and who uses it

This GREENCYCLE MK-521 pack contains ten rolls of 9mm black-on-blue label tape. Each roll is 8m long and fits Brother P-touch label makers such as the PT-65, PT-70 and PT-90. The non-laminated adhesive suits indoor organisation tasks.

The specification that decides fit

The tape width is 9mm, matching the MK-521 format required by the listed Brother models. Using a different width will prevent the cassette from seating correctly in the printer.

Behaviour under sustained use

The adhesive resists water, grease, temperature swings and UV exposure so labels stay legible in kitchens, freezers and on shelving. The split-back liner allows clean removal without sticky residue after long-term application.
