It is not a sturdy construction and its shelves are made of plastic, resulting in not being able to hold heavy weight

It is made of plastic, so it cannot withstand much weight. Personally, I liked it, that's why I ordered it, although the shelves are a bit crooked and not straight. For a place that won't be particularly noticeable, it's fine

The shelves are not metallic and the first one I put on the frame broke, so it is crooked.
