The Brother M-K221 Compatible Tape is designed for use in the smaller Brother P-Touch label printer home and hobby models. Unlike the TZe tapes, the Brother M Tapes do not have the laminated layer to protect the print and are therefore not as durable. However, they are ideal for temporary indoor labelling jobs such as labelling up files, folders, school projects and items around the home or office. The Brother M Tape Compatible range is made from a self-adhesive polyester which gives a crisp, clear print that stands out.
