Nidavellir and expansions organizer for vertical storage

Moosketair's remix is a good start, but I wanted something for sleeved cards and that would support vertical storage.

This does. You can just lift the ready-to-go Treasury out of the box with the handle and pop off the cover. The lower levels of the treasury cover should slide in and lock, but if they are a bit loose, you might want a drop of superglue to hold them in place.

I don't have the Idavoll expansion, but there is a slot for the cards from that. I usually don't want any baggies, but the little tokens from the expansions are so minimal, I have made an exception and just tuck the baggie wherever. There is plenty of space for your favorite small box on the lowest level of the treasury cover if you really need one.

The Treasury straps are delicate to put on, but really help with keeping the shelves in place without needing to glue them. See the picture with picking up the entire thing from the cardboard back and tilting it. Nothing is sliding out.
