We don’t carry out our own tests on use of our permanent markers on ropes or webbing for strap systems. We therefore cannot guarantee the safety of using our markers on ropes and strap systems.
We're aware of tests being carried out by the German Alpine Association on climbing ropes and, on request, we would be happy to send you the latest test result for our black edding 3000 permanent marker.
edding assumes no responsibility for the effects of marking on ropes or strap systems. The many types of material and external influences makes it too complex to assess the effect of ink on a specific material in each case.
