Wire Crates/Wire Shelving

Need a wire shelf system like that cube style? I used these as a bunny run for my bunnies but they passed away 2.5 years ago so these have just been sitting. I have 12 that I am willing to part with at the moment (but I actually have a lot of these). They do not have the little plastic things as most of them broke—and I just used zip ties for the bunny run anyway.
