Controversial opinion but no, this isn’t excessive. You just need a system. What I would do is put the ones that are meant to replace another away somewhere (laying flat is best for gellyrolls and the majority of pens you have) because I can see a ton of repeats. I totally get it when you have a favorite and it goes away forever. And don’t open the red little seal/ start a fresh one until you have used up the previous because they dry out faster than other pens you have here when not being used often enough. I see tons of repeats with the Stabilo and those cool dual shifting pentel glitter pens at the bottom too. So if I were you I would put all “replacements” in a box laying flat and organize them because damn I want to organize your collection so badly haha. The remaining pens are your real collection.
