EC Planner box Die
This Planner box die works in both the Erin Condren (not the neutral version) planner and the new recollections planner. It comes with an extra die so you can make your own custom header as well. This listing is for a die only and there is a separate listing for the happy planner version of this die.
Note: There will be a gap if used in the neutral since that planner has no header but all other dimensions fit fine.
