The green Edding Retract 11 permanent marker features a push mechanism for one-handed operation. So you don't have to remove the cap from this marker, you can use it immediately with the push of a button. This makes the Retract 11 marker ideal for DIY jobs. After closing, the tip is completely retracted back into the pen, so no risk of stains! The green permanent marker has a round tip and puts clear (permanent) stripes on every conceivable surface. The ink is water-resistant, light-resistant and smudge-resistant.
