9 mm Black-on-Blue Label Tape Pack

This five-pack supplies 9 mm wide black-on-blue tape cassettes compatible with Brother P-touch label makers including the PT-45M PT-65 PT-70 PT-80 PT-85 PT-90 PT-M95 PT-100 and PT-110 series. Each cassette holds 26.2 feet of non-laminated standard adhesive tape for indoor labelling tasks such as file folders shelves and storage boxes.

Drop-In Cassette With Split-Back Liner

Installation is a simple drop-in action that matches the original MK-521 form factor so the printer recognises the cassette immediately. The unique split-back liner makes labels easy to peel and apply without leaving sticky residue when removed. No calibration or firmware steps are required.

Fade Water And Temperature Resistant Under

The tape resists fading water grease grime abrasion temperature extremes and UV exposure so printed text remains legible during sustained indoor use. Non-laminated construction keeps the media flexible for curved surfaces while the adhesive holds firmly on plastic metal and painted wood without peeling or cracking over time.

Questions about this item

How do I confirm the tape feeds correctly after installing it in my PT-90?

Insert the cassette until it clicks, close the cover, then press the Print key. The PT-90 should advance a short length of blue tape with crisp black text and no misfeeds.

What comes in the pack and is a cutter included?

The pack contains five 9 mm × 8 m cassettes of black-on-blue non-laminated tape. A cutter is built into each compatible label maker, so no separate tool is needed.

Which cassette model matches a PT-70BM label maker?

The MK-521 cassette is listed as compatible with the PT-70BM and other PT-70 series models, so this 5-pack will work with that printer.
