I ordered these cubes thinking to place them on my shelves, but they were too big. However, they fit perfectly at the top to give me more storage options and to give that decorative, but clean-cut look at the top of my bookcase.  Sometimes our bookcases can be cluttered at the top or not have the right height you are looking for in a high ceiling room. I placed these very nice cubes at the top, I ordered the reddish and brownish colored ones and they are now nestled at the top (giving my bookcase the illusion of being taller in a high ceiling room). These cubes are more sophisticated than the company's regular cubes along with more texture. They were definitely a great buy :)
