OMG I was complaining to myself today about the same problem! I am genuinely grumpy that the pen cap has a bump that basically resembles a pocket clip but isn’t functional. It’s like having pants with decorative pockets!! Now I just need to get a version that doesn’t require me to constantly screw and unscrew the cap for use and I will have less complaints. Thanks for being part of the very niche solution internet stranger!
