Wallet accessories have come a long way since I first started collecting and reviewing wallets. I remember when the humble wallet multi-tool was the only real option on the scene. Fast forward to today, and platforms like Kickstarter are overflowing with unique, creative projects, each designed to be credit card-sized and fit neatly inside a standard wallet slot.

Smokey Creations is the brand we’re focusing on today. Since 2015, they’ve launched 13 successful Kickstarter campaigns, primarily centred around roleplaying games like Pathfinder and, of course, Dungeons & Dragons. Dice are a core element of these games, and Smokey Creations’ latest campaign, the Cardyhedron, has far surpassed all their previous efforts, raising an incredible $278,518, which is more than 6,000% over their original funding goal.

So, what exactly is the Cardyhedron? Put simply, it’s a portable way to roll dice on the go, allowing you to roll anything from a D4 to a D20, all on a device the size of a credit card. Measuring just 5mm thick, the team at Smokey Creations has clearly put a lot of thought into the design. It features six spinning dials, each embedded with micro ball bearings to ensure a smooth, durable spin - similar to the feel of a high-quality fidget spinner.

Not only is the functionality of the Cardyhedron great, especially for avid DnD players, but the design, build quality, and overall craftsmanship are just as impressive. It’s made from a durable zinc alloy, chosen for its balance between strength and lightness. Smokey Creations has also developed a leather card holder made specifically for the Cardyhedron.

At first, I thought this was a nice touch. But then I started to wonder - wasn’t the whole point that it could fit inside a regular wallet? With a thickness of 5mm, I’m not entirely convinced it will slide comfortably into most standard wallet slots. In my opinion, that kind of defeats the purpose of the design if you can’t carry it like any other card.

Of course, I haven’t had the chance to try the Cardyhedron myself, so this is all just speculation - what do you think?

So, what do I think of the Cardyhedron? Honestly, it’s a brilliant idea, and one of those clever concepts I wish I’d come up with myself as a Pathfinder player. The design is impressive, both in terms of functionality and overall build quality. That said, I still have some reservations about its portability. For something marketed as a wallet-friendly device, I’m not entirely convinced it’ll fit comfortably in most standard wallets. And for me, that’s kind of the whole point.
