The Dymo D1 tape, reference 45010, in 12mm x 7m format, black on transparent, is the original tape in the D1 range, compatible with Dymo LabelManager electronic label makers and other models that use this tape system. The black text on a transparent background ensures good contrast and legibility on labels identifying cables, files, shelves, or office supplies. It is a suitable option for those who already use a Dymo D1 label maker and need to replace the original tape with a guarantee of full compatibility with the equipment.
