This TELESIN Protective Case holds your DJI Osmo Action 3 or 4 camera to add an extra layer of waterproof and scratch protection when the camera is not in use. The case can accommodate just the camera on its own or with the metal cage attached. It features a half-open zipper design so your camera can remain mounted on a selfie stick or mini tripod. A velvet lining prevents scratching to the lens and the dual screens.
