Mix and match different designs with the Pochitto Pick Push-Button Stamp! Adding icons and decorations to your planner is as easy as pushing a button. Simply line up the stamp where you want the mark to be, then push the stamp down.  The color of the ink is indicated by the image on the stamp, and the marks are waterproof so you can safely color over them with water-based pens and markers.  This stamp makes six different markings, each of which is approximately 6 mm x 6 mm. This makes it perfect for use even on small planners and calendars. The stamps can be removed from their holder so you can choose to use them individually or all together! It also comes in a clear case to keep the stamps together and prevent them from accidentally marking items when not in use. 

One single stamp is about 1.3 cm x 1.3 cm x 1.3 cm.
