You really won't find many more options without them being custom-made and quite expensive. You just have to get creative sometimes with the things you can find. You probably wouldn't believe the variety of shelving and storage I have for my collection of around 120K cards, if you couldn't see it. I just do whatever works and with whatever I can get my hands on for cheap.
NO PWE's EVER!!! PLZ PM me 1st before sending any offer. ONLY selling cards as of March 2024. No trades or purchases right now.
