So I have at least 3 big packs of the ohuhu markers and it's quite unwieldy to have all those packs and not to be able to store them horizontally the way you're meant to. I've seen those plastic display pen trays like the ones they use for copic markers or spectrum noir. Will those trays fit an ohuhu marker? Because ohuhu markers are quite chunky. I don't want to invest in something that doesn't fit my pens.
