◼︎ Carl Hole Punch - Single Hole ◼︎ 3mm ◼︎ White ◼︎ Boxed ◼︎ New, Unused For punching holes in M5 and M6 size refills. *It may depend on the type of planner, but it fit through the rings of my planner◎ Since the hole is smaller than a general punch, it's also perfect for wrapping, tags, and plastic sheets. Please consider this, as it is stored at home. Thank you. ☺︎
