Bookmark ruler 20 cm for hanging in wire binding or spiral binding

This ruler can simply be hooked into the wire or plastic spiral binding of a planner, notebook or pocket diary from 21 cm length. In addition to the possibility of measuring something or drawing a straight line, the bookmark ruler can also be flexibly inserted at any point of the block and thus also functions as a bookmark.

The bookmark ruler can be used in all diaries, school planners, system planners, organisers and notepads that have been bound with either a wire binder binding (3:1 or 2:1 pitch) or a plastic coil (4:1 pitch) and are at least 210 mm high.
