The iPhone Duo is the phone many Apple users have been waiting for for years. You only have to look at the Duo pre-orders to know that this handset is in serious demand, with shipping times now slipping into 2027.
Unlike the iPhone 18 Pro, the iPhone Duo only comes in two colors: Star White (white) and Night Sky (dark blue), so if you want to make it feel individual, a case is the way to go.
Here, however, there is not as much choice as you might expect. Apple offers two case designs, both available in just two colors. There’s the standard polycarbonate case in either sand (cream) or navy blue, and there’s the TechWoven folio case in either taupe or navy blue.
That gives you just eight combinations between phone and case. Third-party cases have also been slower to come through, but some of the biggest names have offers to give your folding phone a little more character. All of which you will find below.
While it may seem a shame to hide such a beautiful new design under a case, the last thing you want to do is scratch or break your new duo, especially when you consider the potential repair costs. So putting a case on it gives you extra protection.
All these cases are specially designed for the latest iPhone Duo model. You can find cases for the iPhone 18 Pro and 18 Pro Max models here.

ArmorGrid Air Beyond Blue Case built with Kevlar for iPhone Duo
Prices from £82.20 / $109.99
Benks not only brings beautiful designs to its cases, but it also brings serious power. The ArmorGrid Air Grand Combo uses Kevlar to give it strength and remains lightweight (there’s a reason it’s used for bulletproof vests). This model includes a front frame, back cover and screen protector, but no hinge guard. It also comes in an Obsidian Black version, as well as a see-through case without the Kevlar protection.
