The stone pen is a Swiss-made writing instrument crafted with 60% calcium carbonate, the same core material as Karst paper, giving it a premium weight and perfectly balanced feel, around 50% heavier than standard plastic pens. Its Floating Ball® ink system delivers a smooth, bold line with up to 200% richer ink density and ultra-fast drying in just 1-3 seconds on stone paper, ensuring a clean, smudge-free writing experience. Designed with a hexagonal body, matte finish, and integrated steel clip, it offers comfort and control for everyday writing, sketching, or note-taking. Free from phthalates and harmful substances, the pen writes up to 5,000 meters and is built as the perfect finishing piece of the Karst writing system.
