Post-it Style Kit (Planner Kit) Can be inserted into your favorite planner. This item is unused, but the top of the binder holes is cracked, so the price has been reduced. No claims/No returns, please. If you have a 6-hole binder planner, you can use it as is. For a regular planner, the 6-hole section on the spine is perforated, so please cut it out and insert it into the back pocket of your planner. Size: 17 x 9.5 cm
