Strona Adjustable Corner Shelf Black

Hello I don't know a whole lot about this I just got it in a random box, mystery box. It's metal shelving the box is a good weight considering it's size. I don't know how big the shelves are the boxes about 12x12. It's black it goes in a corner looks like there's different options. If you're looking for this sort of thing you probably know more than I do about it lol.
