Setup, Compatibility & Care
To ensure the longevity of your Edding 330 markers, store them horizontally whenever possible to keep the ink flow consistent across the chisel tip. Always replace the cap firmly after each use until you hear a click to prevent the solvent-based ink from drying out prematurely. If the marker has been left uncapped and the tip appears dry, you can sometimes restore function by recapping it for an hour, allowing the ink from the reservoir to re-saturate the nib. The markers are compatible with most standard surfaces but should be tested on a small, inconspicuous area if you are concerned about permanence on highly porous materials or sensitive plastics.
