A new era of the Twin Marker has just begun - after 3 years of development in cooperation with Schneider Schreibgeräte GmbH. The Twin Marker produced in Germany consists of 95* recycled plastics. Thanks to a cartridge exchange system with a robust and hearable locking function, up to 56% of plastics can be avoided when buying a new cartridge instead of a complete marker. This means 10.6 g less plastic! The exchange of the cartridge is done when caps are closed by screwing the cartridge.
