Ultimate Guard Arkhive 400+, Deck Case for 400 Double-Sleeved TCG Cards, Black, Compatible with Boulders, Magnetic Closure & Microfiber Inner Lining

The Ultimate Guard Arkhive is an incredibly well-made storage solution. The materials feel premium, the construction is solid, and the size is perfect for anyone needing to store a large collection of cards. I was genuinely impressed by the overall quality—Ultimate Guard never disappoints. Ultimately, I ended up returning it because it didn’t quite match the specific storage needs I had in mind. That said, if you’re looking for a durable and spacious deck/cube box with a sleek design, this is a top-tier option.

This is too good. I can't use anything else now. I have two Arkhive 800+ and a 400+ along with an assortment of boulder deck cases. Target price is ~$45 for the 800+ and ~$30 for the 400+, wait for your preferred color(s) to be a good price if you can The dragon shield magic carpet is the only other intriguing case for me, but pricier and I'm not sure if the incorporated playmat is the right move. If you like the folded playmat/cover.... great! You now have a portable playmat that takes up ZERO space. But if you don't like using that as a playmat then I see no upside, a higher price, and poorer build quality/durability. If you're a fan of the Ultimate Guard boulder then this is a no-brainer, this is THE case for your deck boxes. If you prefer using some of the larger deck boxes it may not be ideal. Oh yeah, insanely satisfying to just store sleeved cards in here too. Boulders aren't much larger than sleeved cards, so you don't have annoying empty space for cards to jostle around... everything sits nice and tidy PS: about boulders, since they are relevant to anyone who has this box... it seems like there was a brief period where production was of poorer quality. The old ones are great, and the current ones are great, but there seems to be a time period where you could buy one and the coating would be able to flake off at the corners of the boulder, revealing clear plastic underneath in patches. I've bought from three different sources recently, and two of them supplied perfect boulders, while the third source provided boulders which were flaking OUT OF THE BOX before seeing any usage. Make sure to eye over any you may buy so you can immediately return if defective.

This is my second Arkhive purchase. Previously bought the smaller size which I like as well. Smaller size I keep my MTG Jumpstart packs where they’ve been “cubed”. I like the versatility of being able to keep deck boxes or singles, sleeved, I sleeved or double sleeved. If they were less expensive believe me - I would buy many MANY more so all of my cards (even bulk) could be stored in these. Even fully packed with singles the container structure is sturdy. The exterior seems resilient as well. For travel I’d suggest the smaller Arhive as the larger gets very heavy. All in all I’m very happy and will continue to purchase this product for safe storage. Absolute bonus that they look fantastic compared to other options! A bit of an “adult” upgrade to cardboard, I feel like these can be showcased.

I have had every box you can buy and let me just say UG stuff is the top of the class when it comes to boxes. I'm not a huge fan of their sleeves but the boxes are mint quality. Love this design with the vertical instead of the traditional horizontal sit. I can just easily grab my decks out of the box, no trying to fish them out like with other traditional multi deck boxes. Pair this up with the UG dividers as well and you are good to go. It is a little smaller than most boxes in this class. The 400 double sleeve is the absolute limit. So if you are going to have tokens you will not be able to fit 4 in comfortably. Even so, the design here is so much better that getting stuff out is a breeze as opposed to traditional boxes. I will be switching all my stuff over to these soon and I'm cool with rocking only 3 decks in a box with the tokens as opposed to 4. Also, if you have some single sleeve budget commander decks or any 60+15 format decks, drop those in with a double sleeved or two and there's your min/maxing the box.

Gifted to my brother for his gigantic collection of magic cards. He seemed pretty chuffed with this box. Sturdy, good storage capacity, very functional.

Bought this because it was getting tedious transporting all of my MTG 60 card decks to my local LGS each week, or even to the kitchen when my wife wants to play. This holds 12 ultra pro 60 card deck boxes (the cheap ones that are $10 for 5) or other similar boxes perfectly and securely. Bought another one to transport my commander decks, which it will hold 6 of with a bit of room in each side for tokens, so they might slide around depending on the deck bokes. If you use ultimate guard boulders, it will fit them perfectly.

DOES hold Ultra Pro standard size and 100 + deck boxes (6 of the 100+ and 2 standard if that's all you put in the ArkHive). DOES fit the smaller trays that come in M:TG Fat Packs. DOES fit M:TG preconstructed Brawl Decks in their boxes. DOES fit Card Kingdom's slightly taller divider cards. Great for vertical storage of M:TG cards with UG or UP dividers between them. Handy for flipping through cards when building decks. Also, the fold out lid make a great cushioned tray so you can drag cards around without scratching them. The magnet lock is very sturdy. DOES NOT fit OOPIN brand card boxes with the leather-like cover (left side of picture, spider web design). DOES NOT fit the long trays that come with M:TG Fat Packs (left side of picture).

Great storage box that offers good protection for your trading cards. The magnets on the lid are strong and won’t open easily, unless forced. The construction seems to be durable, with high-quality materials, and there is enough space inside that you can fit a few deck boxes, cards and/or top-loaders. My only complaint is that if you are using Ultimate Guard 100+ sidewinder deck boxes, you won’t be able to fit in 4 of those, only 3. But it’s fine, the extra space can be used for other things. Highly recommended!
