Review on Black Cube Storage Shelves by AmazonBasics by Brandon Garrett

I did not use them for their intended purpose but they are very strong and I was able to change the way the cage is mounted very easily. With their help, you can build a large, comfortable cage for your pets. I had a two story house and the top was strong and held up great when my little fat guinea pigs ran around. I ended up making it longer and I have plenty left over to make the top. As you can see we were able to bend some of them to make a tunnel and the girls love running and walking under them. I plan on ordering more to stand for and add some width and length!
