Super Famicom Cart Storage

I can’t find those dish drying racks and I’d rather not drill holes in my wall anyway. So this Super Famicom storage unit would be really cool to own. SFC carts are special pain in the ass because they can’t be stacked on top of one another. That means they’re hard to pack into a small space and it’s impossible to know which cart you’re going to pull out unless you’ve memorized which games are where.
