Apple's iPhone Duo Case uses adhesive to attach to the device, according to people who have picked one up.
The case comes in two pieces and uses adhesive strips along the inside edges to attach securely to an iPhone Duo. An included insert instructs users to peel off the adhesive's protective film, put each half on the Duo, and then press down to make sure it's well-adhered.
The iPhone Duo Case is made from polycarbonate and comes in Sand and Navy Blue. It is designed to protect the back of the iPhone where the camera bump is located and the front around the outer display. It has a cutout for the front display, and no protection for the inside of the device when it's unfolded.
the folio is clearly the nicer one, the kickstand feels sturdy (the hinges are metal underneath) but the case has a nice grippy feel to it though it has the adhesive stickers like other foldables — Parker Ortolani (@ParkerOrtolani) October 16, 2026
Apple also sells the iPhone Duo Folio with Kickstand, and that case does not use adhesive. It attaches to the iPhone Duo magnetically, but it does not offer protection for the sides of the device and it covers the front display when in use. It uses magnets to make it easy to fold back if the outer display is needed.
iPhone Duo pre-orders began today, and the first devices won't arrive to customers until next Friday, but cases are in stores today. Initial iPhone Duo stock sold out, and shipping estimates are now at January 25 for all colors and capacities.
The iPhone Duo Folio is priced at $129, and the iPhone Duo Case is priced at $79.
