Before I got into using planners a few years back I had no clue how large the community was. Planning is more than just another hobby. For many people it’s a way of life because it gives them control over their time, which in turn decreases anxiety and scatterbrain. If you have a planner in your life trust me when I say there’s really no such thing as too many accessories for them.
They already have all kinds of planner related crap! What more could they possibly want?
