Most complaints about cases are that they don't fit properly and AirPods pop out of the case. With an Elago case, this is something you never have to worry about. All cases are created with our own 3D mold, so you know that what you get is made exactly for your product - meaning all functions, like wireless charging, work with no problems! Strap is included with the order. Keep it close and never lose it again with the Elago strap. Nylon is lightweight and durable, so it doesn't add any weight but offers additional protection from loss and drops! The loop can be adjusted easily with the button adjuster. Premium silicone material protects your charging case from everyday use, including dirt, oil, scratches and drops. Silicone also provides great grip and a slim profile, allowing it to fit in your pocket!
