As for me I mainly use the Dragon Shield Storage Boxes or Game Boxes If there's any still available which I consider superior to the Ultra Pro 100+ 2-Piece Gaming Boxes since YOU HAVE TO PUT THE CARDS IN SIDEWAYS as they'll get stuck on the bottom and damage your cards If you put them in with the face or back sticking out. The LGS I go to on Saturdays have the Ultra Pro Satin Towers which I'm not too crazy about since they're not small enough to fit in my Pirate Lab Game Bag that I've been using since Ultra Pro stopped manufacturing Game Bags with Styrofoam inserts and replaced them with cheap cardboard. I know Ultimate Guard used to have the "Bricks" however it doesn't feel as comfortable for me as their Katana Sleeves which have more durability than Japanese KMC Sleeves where there's not as much wear and tear.
Definitely feels like we're WAY overdue for a company or manufacturer to develop a 100 count Deck Box for EDH / Commander with the highest quality and simplicity available. The colors of the Dragon Shield Storage Boxes and Game Boxes I already own feels tacky to the point where I'm tempted to tape designs on it that's cut out from printing MTG designs through an Inkjet Printer which I don't have unfortunately especially with printer ink being expensive as it is and all. So far me and my friends at my locals already have 6-7+ EDH / Commander decks built but due to all the spending through Stimulus Checks and Tax Refunds it's almost impossible to find the right deck box to store these decks especially when the manufacturer refuses to make more of these products as there's no price increase to make up for low supply and high demand.
I figured since my LGS has access to a 3D Printer that I'd try to get Dragon Shield Storage Boxes / Game Boxes printed off which according to a friend of mine whose used it to print miniatures for his Dungeons & Dragons campaigns that the deck boxes would cost me roughly $5 per box (both lid and holder) which isn't bad actually. Unfortunately the person I need help getting the deckboxes made doesn't work during the weekends as he's only available during the weekdays though I'm hoping he'll help me get it figured out somehow. Just need to contact his e-mail or call so I can get the deck boxes printed. Thing is Dragon Shield Storage Boxes / Game Boxes are almost hard to come by nowadays due to the popularity of the EDH / Commander format.
