Twelve large A2 pages printed on Karst's signature stone paper give each month its own dedicated sheet, torn away or flipped as the year progresses — built to survive a full year on a wall without curling, tearing, or fading the way wood-pulp paper eventually does. The same waterproof, tear-resistant material used across Karst's notebook line carries over directly to the calendar format.

Displayed one month at a time as a monthly ritual, or hung together as a full twelve-page spread for a bold year-long overview, it's built to stay legible from January through December without visible wear.
