These markers allow users to write their own cable designation and are suitable for cables from 3.5mm to 16mm. Each marker comprises a white PVC write-on area, which can automatically be protected from rubbing off or smudging by wrapping the transparent film, which comprises the rest of the tape, over the written area. All markers include a break-off tag to avoid adhesive contamination of the end by the fingers. Markers are supplied on booklets (priced per booklet).
