I'm 70 years old and getting ready to move into a retirement community. These small boxes are perfect for my books. Even when filled to the top, I can still pick them up and carry them despite 45 years of rheumatoid arthritis. The boxes are inexpensive so I can afford to use several smaller boxes rather than one large one (which I wouldn't be able to pick up). They are sturdy, easy to put together, and provide protection for precious books including a first edition Rebecca by Daphne DuMaurier. Love the lids.
