Apple's $79 iPhone Duo Case uses adhesive strips
Apple's $79 iPhone Duo Case uses adhesive strips to attach its two halves, while the pricier Folio uses magnets and adds a kickstand.
Apple's $79 iPhone Duo Case uses adhesive strips to hold its two halves in place, according to MacRumors reports from people who have handled the accessory.1 The case is now listed on Apple's own shop in Sand and Navy Blue, while the company's product page confirms that it is a two-part polycarbonate case designed for the foldable iPhone Duo.2
The adhesive sits along the inside edges of the case. Apple's packaging instructions tell owners to peel away the protective film, fit each half to the phone and press down so the case adheres securely. That is a different approach from the iPhone Duo Folio with Kickstand, which attaches magnetically and costs $129 rather than $79.1
Apple's official product page describes the standard case as thin and light, with protection around the front and back exterior of the phone. It leaves the inner display uncovered when the device is unfolded, while a camera cutout keeps the rear camera hardware accessible. The case also has built-in magnets for alignment and wireless charging, according to Apple.2
The choice matters because the iPhone Duo Case is not just a conventional snap-on shell. Once the adhesive strips are pressed into place, removing or repositioning the case is likely to be less convenient than switching between a magnetic accessory and the phone's bare finish. Apple is selling the product alongside the more expensive Folio, giving buyers a choice between a lighter adhesive-backed design and a bulkier cover with a kickstand.1
The iPhone Duo Case is available for $79, while the Folio with Kickstand is priced at $129. MacRumors reports that cases are already in stores, even as iPhone Duo shipping estimates have moved later for some configurations.1 Apple's shop lists the Case as compatible with iPhone Duo and shows the Sand model as available to order.2
Our opinion
The adhesive detail is the interesting bit here, because it changes the ownership experience more than the colour options do. A case that needs to be pressed into place may fit tightly and avoid the looseness some foldable accessories develop, but it also makes experimentation more awkward. Apple at least offers a magnetic alternative, so buyers are not forced into the $79 design — but anyone who regularly swaps cases should look closely at the Folio before choosing the cheaper option.
