Our inspiration comes from the silverpoint technique of Leonardo Da Vinci, hence the patented ETHERGRAF®️.ETHERGRAF® is an innovative metal alloy that “scratches” plain paper by oxidizing it and leaving a light and romantic trait like that of graphite, as timeless as ink. It can write on any type of paper except glossy paper and post-it.The ETHERGRAF® is lead free and it has zero side effects on health
