iPhone Duo Cases & Stone Backs

Real stone for the iPhone Duo, Apple’s first foldable iPhone. First up is the Fusion Snap: a magnetic back in milled aluminium with a flush marble veneer that snaps onto the Duo and comes off in one move. Not a case, not a skin, just stone and metal.

There is also the Slate Skin in real slate, in Transocean and Black Rock. Cases are coming next. Every piece is made to order in our workshop in Germany, and is one of a kind. Which stone suits you? · All stones

Stone for the iPhone Duo – frequently asked questions

What is the Fusion Snap?

A magnetic back for the iPhone Duo: aluminium milled from solid with a veneer of real marble set flush inside. A magnetic ring holds the Snap to the iPhone, one move takes it off again. It is not a case and does not wrap the iPhone.

Are there cases and skins for the iPhone Duo too?

Yes. The Slate Skin is available for the iPhone Duo in two slates: Transocean and Black Rock. Genuine stone, around 1 mm thin, for the back and camera plateau, with the hinge left clear. More stones and cases will follow.

When will the Fusion Snap ship?

The Fusion Snap is a pre-order from a first, small run. The ship date is shown next to the price on the product page. We make pieces in order of purchase and let you know as soon as yours is ready to ship.

What happens if the stone breaks?

Every piece comes with a Stone Passport. If the stone breaks within 12 months of delivery, we make the same model in the same type of stone again at half price, once per passport, plus shipping. More about the Stone Passport.

Which case fits the iPhone Duo?

Because the iPhone Duo folds, we built a back instead of a case: the Fusion Snap in aluminium and real marble. It sits only on the back, and the hinge stays free.

Does wireless charging work with the Fusion Snap?

Yes. Wireless charging works right through the Snap, and MagSafe chargers attach directly. A ring of 36 neodymium magnets holds it in every position.
