【Secure Lock Function】This Airpods 3 case adopts the latest secure lock function. You can only open the Airpods 3 by pressing the [open] key. Therefore, with this function, you don't have to worry about the earphones popping out when dropped, or accidentally opening them in your pocket or bag and losing them. 【Strong Protection】Made of high-quality and durable TPU, with reinforced bumpers on all four sides, and an air cushion formed between the bumper and the protective cover, it effectively absorbs shocks and protects against strong impacts from drops. 【Carbon Fiber Surface】The carbon fiber surface is beautiful and simple, not only resistant to dirt and fingerprints, but also scratch-resistant, so you don't have to worry about scratches even if you put it with your keys. The inside is smooth to prevent scratches on the Air Pods 3 body. 【Exquisite Cutouts】The LED hole design allows you to see the status light even with the case attached. The earphone box on the back also supports the "reset button," making it easy to find and use. 【Convenient to Carry & Anti-Lost】You can carry it around by attaching it to your waist or bag with the included aluminum carabiner.
