STABILO's most sustainable fountain pen STABILO Grow combines design, quality and sustainability. Perfect writing comfort, maximum leakage protection, a robust steel nib with integrated iridium grain and an ergonomic grip zone ensure perfect fountain pen properties. But the product is also extremely environmentally friendly. The use of renewable and recycled raw materials reduces the amount of virgin plastic used and thus the CO2 consumption from raw materials compared to a fountain pen made from fossil-based plastic. The product shaft is made from oiled wood from 100% FSC®-certified, sustainable forestry.
