Ninja Labs has released the MagSafe Flex Pouch, a stretchy silicone storage pouch that attaches magnetically to the back of an iPhone, for $58.

The Verge reported the launch on 16 October, describing it as a magnetic wallet that holds far more than a few cards. Ninja Labs, a Los Angeles accessory maker, already sells the Flex Pouch as a one-piece iPhone case with the pouch moulded into its back, at $78 for the iPhone 18 and iPhone 17 models. The new version drops the case. Ninja Labs' product page says it is not a phone case, and that it snaps on and off any MagSafe-compatible phone or case.

What does the MagSafe Flex Pouch hold?

Ninja Labs gives no volume or dimensions. Its page describes capacity by example: from one card up to 20, plus AirPods or other earbuds, a car key fob, cash and coins, and lip balm or small cosmetics. It warns against anything with sharp edges, naming ordinary house keys, because they can puncture the silicone. The company claims the pouch kept more than 90 per cent of its stretch after 10,000 stretches.

It comes in pink, baby blue, lavender and black, each with either a clear or a matching pouch, and a pink version with a glittery Princess Sparkles pouch. Ninja Labs charges $10 for shipping worldwide, quotes 7 to 10 days for delivery, and accepts returns within 30 days.

The original case was not MagSafe compatible, according to the Macworld review Ninja Labs quotes on its own site. That was the trade-off: a case with a pouch, or a case that works with magnetic chargers and mounts. The add-on is the company's answer to it.

Which iPhones does it work with?

Ninja Labs says only that it is for iPhone and attaches to MagSafe-compatible phones and cases, without naming models. MagSafe arrived with the iPhone 12 and is on most models since, though the iPhone 16e left it out. The page does not state magnet strength, the pouch's size or weight, or whether it works with MagSafe chargers, stands and car mounts while attached.

Apple's own guidance applies to anything carrying cards. Its support page on the MagSafe Charger says credit cards, security badges, passports and key fobs should not sit between an iPhone and the charger, because the magnets can damage magnetic strips and RFID chips. Apple says to remove them, or make sure they are not behind the phone, before charging.

Our take

A clip-on version is the more sensible product. A pouch built into a case means the case decides everything: change phones and the pouch goes in the drawer with it. A MagSafe pouch moves from an iPhone 13 to an iPhone 18 to whatever comes next, and it comes off when the phone has to go on a charger or into a car mount. At $58 it is also $20 less than the case.

What it cannot do is beat physics, and that is where APPDOOK would want to see it tested before recommending it. MagSafe holds a slim wallet of a few cards well. A pouch carrying AirPods and a key fob is a heavier load, with its weight sitting further from the magnets, and Ninja Labs publishes nothing on hold strength. Anyone planning to carry their car key in it should try it with something cheaper first.

Three practical points for anyone buying one:

• Take it off to charge. Apple's warning about cards and MagSafe chargers covers exactly what this pouch is designed to carry, and a stuffed pouch will not sit flat on a charger anyway.
• Check the fit with your case. Ninja Labs says it works through MagSafe cases, but a thick case weakens any magnetic hold.
• Keep sharp keys out. The maker's own warning, and the one way to ruin it.

The iPhone Duo is the open question. MacRumors reported from Apple's tech specs that it supports MagSafe and Qi2 at up to 25W, and it ships on 23 October on iOS 27.1. But BGR points out that the folded Duo is 4.61 inches tall and 3.31 inches wide, close to the width of a card, so most MagSafe wallets either hang below the magnet ring or fail to align. Even Apple's own iPhone Duo Case sticks on with adhesive strips rather than magnets. A pouch that stretches might cope better than a rigid wallet, but Ninja Labs has not said, and we would not assume it until someone has tried one.
