The Ultimate Hybrid Setup: Really Useful Boxes + Tabletop Tyrant Cases

If you're a hobbyist in 2026, your army probably lives in Really Useful Boxes. Magnetised, stackable, and infinitely reorganisable — they've become the storage standard for good reason.

But there's always been one nagging question: what do you actually carry them in?

We went out, bought the industry-standard 9-Litre Really Useful Box (A4 size), and put it to the test with our Dreadnought Army Case. The fit is perfect. Because our bags are built around standard A4-footprint foam trays, they naturally accommodate the entire A4 RUB range — no adapters, no compromises.

What fits in the Dreadnought?

The Dreadnought comfortably holds 2 × 9-Litre RUBs alongside a foam tray, making it ideal for armies that mix magnetised storage with fragile models you'd rather keep in foam. The 9L boxes are perfect for taller models, vehicles, and monsters; if you run smaller infantry-heavy forces, the 4-Litre RUBs sit just as neatly. Any bin with an A4 footprint will work.

Why the hybrid setup beats going all-in on either system

Foam-only cases ask you to commit to one way of working. Bin-only setups leave you carrying three plastic boxes by hand — which is fine until it isn't, usually somewhere between the car park and the venue door.

The hybrid approach gives you the best of both. Magnetise at home, pack into a Tabletop Tyrant bag for the road. You get waterproof protection against the British weather, proper shoulder straps, and enough pocket space for dice, cards, and a rulebook — all wrapped around the storage system you already use and love.

Stop buying into proprietary ecosystems. Bring your bins. We'll handle the carrying.

Which cases work with Really Useful Boxes?

The short answer is that most of our range is compatible — but the right case depends on how tall your bins are stacked.

The Dreadnought, for example, holds 2 × 9-Litre RUBs alongside a foam tray, making it a natural fit for armies that mix magnetised storage with fragile models. Smaller cases in the range will accommodate 4-Litre RUBs and shorter stacks, but the 9L boxes may be too tall depending on the case's internal depth.

The rule of thumb: if your RUBs have an A4 footprint, they'll fit the width. Whether they fit the height depends on which case you choose and how many you're stacking.
