I stuff my planners, and the standard 25mm rings just seem so…tiny! And when you order a van der Spek, you can choose 35 mm rings!! And of course I did. I love the possibility to customize your planner, although it meant it took me forever to decide on colour, stiffener or no stiffener, back pocket or not…. Petra van der Spek has the patience of a saint!! And finally, my A5 made it home!!
