The pack of 15 book boxes worked well, enabling us to pack up books in an orderly manner. The boxes were bigger than I had expected, so in most cases we packed them 2/3rds full and finished with cushions to give padding without adding much weight. This method worked very well, and kept the books firm during the moving process. The boxes were also useful for breakables, this time, padded above and below with blankets, and individual items wrapped in bubble wrap. Overall these boxes were an excellent purchase, we were very happy with them.
