The 0.6mm Ironlak Permanent marker is the optimal pen for adding medium sized main points to drawings and text. The ink formula used dries in seconds to a smudge and water-proof finish leaving no room for messy mistakes. The standard soft nib wont damage sensitive surfaces (such as CD’s and the like.) and these pens are completely airplane secure making them a really perfect go back and forth companion.
