The Dymo D1 tape, reference 45021, in 12mm x 7m format, white on black, is the original tape in the D1 range, compatible with Dymo LabelManager electronic label makers and other models that use this tape system. This high-contrast combination, with white text on a black background, is ideal for a more elegant look or for identification in low-light environments. The white text on a black background ensures good contrast and legibility on labels for 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 guaranteed full compatibility with the equipment.
