This pen features carbon-infused concrete. Concrete and plastics can be improved through material additives that add flexibility and strength. Carbon Upcycling Technologies makes nanomaterials from CO₂ emissions sequestered into solids, like fly ash and graphite. Their technology sequesters between 50 - 150 kg of CO₂ per ton of material. This pen was designed by 22 Design Studios and is available on the Skybaron marketplace.
