MediaRange Label Tape Cassette for Dymo D1 91225/S0721700 12mm x 4m Black on Blue

With a 4-metre continuous polyester tape that shrugs off water, UV, abrasion, chemicals and temperatures from -18°C to 90°C, this cassette keeps your labels readable in almost any environment. The 12 mm width fits Dymo D1 printers and replaces the original 91225/S0721700 cartridge directly.
