This Perpetual Calendar Stamp's by Shachihata is a super compact calendar stamp that allows you to customize and create mini-calendars wherever you need them. Instead of manually creating calendars each month in your planner or carrying another planner entirely just for a monthly calendar, you can have the option of condensing your needs into one place using this stamp!
The stamp uses concave and convex mechanisms that allows the pieces to be fitted together both vertically and horizontally, so you can create a stamp for any month of the year. However, we have found that it works best if you first stack the pieces in one direction first, then connect them in the opposite direction (eg first connect the pieces horizontally, then stack them vertically).
Shachihata is known for making fast drying oil-based stamp pads. Using them together with any Shachihata ink pads, you can easily enhance your planning whilst keeping it simple!
