The Infinity Box // Self-Build


This box is fantastic. The build instructions were very clear and made for a fun evening project. The final product is a super slick-looking, heavy duty storage solution that I would recommend to anyone involved in an expandable card game. I'm storing Arkham Horror in this, and currently have the core campaign, plus 4 full campaigns and a standalone, with plenty of leftover space for my token box, wooden after market player boards and act/agenda holders, chaos tokens, 7 built decks, and a few boxes of sleeves. I suspect with all existing campaign content (core + 9 full campaigns), it might be pushing the limits of this box and the decks/tokens/boards/sleeves would certainly have to live somewhere else... that said, anything larger than this would be too much. There are a lot of dividers included, and they make it very easy to divide up the space as needed. The top tray is fairly shallow, so there is a limit to how many campaign books can fit (only because they're spiral-bound), but plenty of space for a couple of those, plus the rules reference. Note: I keep my player cards in binders, but be aware that a complete collection at this time (May 2024) would require 2 Infinity boxes.


Clever design, great bulk storage solution to organize your cards as well as all the inserts, manuals, and tokens that tend to go along with them all in one tidy (albeit heavy and large) place. Recommend getting some token boxes as well. Assembly does take some real patience, steady hands, and a bit of care, but anything made well usually does;) Some thoughts now that I've got one built and loaded up with Marvel Champions: - The main insert is well designed without any wasted space to keep the row width of cards very compact - I would maybe challenge the claim of 4,884 sleeved capacity (FFG, 90 micron) my experience fully loading a row with Marvel Champions cards in a practical way (tightly fit and compressed but allowing a few mm cushion at one end so the cards can be retrieved without crushing them in) using 100 micron sleeves clocked in at 600 per row as a reasonable max (or 3,600 total across 6 rows total capacity) even at a 10% variance from 90 micron sleeves, trying to fit over 800 sleeved cards per row feels ambitious. - Would have loved the option for the token boxes to be stored upright to allow for more card space in the channels. That would reduce the amount of tokens that could fit I suppose, but as they are you need to store them flat and stack them horizontally if you want to fit the top tray on (which you definitely do). - Would be nice for the top tray (which is great) to have been double the height to allow for additional manuals, inserts, hit counters, and log book, etc. It comes at around 1cm depth and still does the job for most needs, but it's very slim. Overall, very happy with this purchase - will buy again for other collections. Paired with the well-crafted dividers on offer here, the Infinity Box provides a practical, clean, and organized way to store otherwise unwieldy, overwhelming, and over bloated packaging LCG games tend to stack up as you add to your collection. I've tried a few different solutions including the BCW cardboard "Monster" box, and Gamegenic "Dungeon" boxes which either require several boxes (defeating the point) or are spread out extremely wide and impractical to carry (without lid headroom for dividers). The Infinity box is the cleanest and most practical solution I've tried.


Purchased this box recently after my collection outgrew my previous storage solution. This is absolutely excellent! The assembly is surprisingly easy so I recommend doing it yourself to save some money. The box itself is very sturdy and comes with A LOT of wooden dividers! I have two of these boxes for my arkham collection and I've fit everything into two boxes. Will probably order another in the near future

After buying a couple of dividers and seeing their quality, I couldn't stop myself from buying this box and it was one of the best purchases I have made for LCGs in years, and definitely the best storage option. I'm pretty sure I would need two of them just to store all of Arkham Horror or LOTR (ok, maybe three), but still has space for a huuuuge amount of cards. The quality of the box is really good as well and the assembly is really simple if you're careful enough and don't spread glue all over.


Great box! everything fits well including a play-mat, rule books, tokens with room to spare and that’s just the included tray. Definitely the best option if your collection is large already or you’re planning to add to the collection you have.


We purchased this box through the Etsy store last year. Absolutely love it. It's incredibly sturdy with an insane amount of space. It fits all of the content released so far, and there's still so much space for the future of MC. It also fits all of my tokens from BTST and the player boards, and villain boards. I researched different card boxes leading up to getting this one, and I can honestly say I believe this is the best option out there.

The Infinity Box is our solution to large card game storage. Be it Marvel Champions, Arkham Horror The Card Game, The Legendary Series, Pokémon, Aeons End, Keyforge or Warhammer Underworlds this box will keep your collection together with room for additional cards as the game grows.


  •     Un-sleeved capacity (using FFG LCG cards) = c.6,564
  •     Sleeved capacity (90 micron) = c.4,884
  •     34 MDF dividers (our latest 'Dobby' design which can fit side by side in adjacent channels)
  •     Internal Dimensions: 338 W x 432 L x 116 H (mm)
  •     External Dimensions: 350 W x 450 L x 120 H (mm)
  •     Enough depth to store standard american card game cards fully up-right with sleeves and dividers
  •     Black matte laminate outer, white inside
  •     Magnetic full front flap lid
  •     12mm deep top tray for rulebook and miscellaneous storage
  •     6 Vertical Storage Card Channels (c.70mm width)
  •     Our token boxes will only fit into the card channels, not the top tray.


  • Good quality PVA or strong wood glue (I use PVA from a trade merchant), ideally with a thin 2-3mm dispenser tip, a bit like a ketchup bottle or similar. Gorilla Wood Glue, Loctite Wood Glue etc. should be fine.
  • Masking tape (Ideally low tack)
  • A flat surface and a mat or something to protect your table (PVA Glue is water soluble and can be removed with a bit of elbow grease and a damp cloth but better to not get it everywhere in the first place as my wife keeps telling me!)
  • About 1 hour building time + few hours drying time in between steps (and ideally over night once finished)
  • Some patience :)


  • A paint brush to level out glue (large brush is good, around 8mm width is what I use, or you can use your fingers)
  • A pot of water to clean your brush.
  • Kitchen towel or cloth to wipe up excess glue, soak excess water from your brush and clean up mess.

Every piece of the MDF box insert is unique and you cannot put the wrong piece into the wrong slot. You can also use either side of all pieces though we suggest the side with the least laser burn marks should be the side showing.

You do not need cutting tools to remove the MDF pieces. Just pop them out with your finger. If there is a bit of wood preventing a smooth connection between 2 pieces then a light sanding or shaving will help but in general this shouldn’t be required.

We recommend dry-fitting pieces together before gluing so that you get a good idea of how each piece fits. This might add time to the build but is often worth it.

This box is HUGE. It weighs in at over 3.5kg when packed for delivery!

It DOES NOT fit in a Kallax unit - but we are looking at a smaller box for this.

It is designed to be stored on its base, NOT vertically.

There are lots of custom vinyls on Etsy that you can brand your box with or use a website such as Avery to make a custom one.

Please contact us if you want multiple Infinity boxes as a custom shipping quote will be required.

A burnt wood smell will be present when you first open your box, this is from the laser cutting process and should fade over time.

Our vertical dividers fit perfectly in this box.
