I want to sell this, so I've lowered the price. The box is a little over 3cm thick, so I will fold the box for shipping. [Compatible Models] GoPro Hero12/11/10/9/8/Max/7/6/5/4/2018, OSMO Action, and other action cameras. [Notes] For Hero8 without a cover, the short screw will interfere with the Hero8 camera body. Please use it with the cover attached. [Metal] The thumb screws and wrench are made of high-quality aluminum alloy, making them sturdy and durable. [Easy to Use] The aluminum wrench makes it easy to tighten the screws, and you can use the wrench to secure them firmly. [Rubber Rings] Small rubber rings are included to prevent wear and tear. Put them aside when not needed. There are no noticeable stains. Thank you for your consideration.
