It comes with a new, waterproof case as the original fund and 3 to insert the screen into the case with his GoPro: An open bottom, a tight bottom in order to use the touch screen (under the eg water) and a completely closed bottom.
Be careful when opening the product to thoroughly check the GoPro as the back of the cardboard box contains two funds that have well almost from the trash! : P
I recommend. Thank you Amazon for its quality of service!
