Great! You do need a rivet tool.
"Cargo net is actually a bit smaller than what you see in the photo. Maybe the soccer ball isn’t a full adult size? Who knows. Anyways, I was able to put some cleaning bottles there to prevent them from moving around and used the left side cargo net for my air pump and first aid kit. 10/10 gives more space. Good mesh material. Now, you do have to move out the weather strip that is pretty easy, and you need some prying tools (plastic) to lift up on the hard black plastic. Once you take that out, you put the supplies rivet bolts inside the holes and use the rivet tool to make them stay in there permanently. Make a hole around the black plastic and put the rest of the supplied parts on it and you’re set. Sounds complicated but it was pretty easy. Definitely get a rivet tool as it does not say you need one until much later."
