Where should you put that extensive old vinyl collection that you had for years after your last record player was given to the Salvation Army? The Offi & Company Perf Boxes designed by Eric Pfeiffer. Of course just because they are the perfect size for LP's doesn't mean you shouldn't use them for books. In fact order several and make a wall of Perf Boxes. These babies rotate and you can choose to attach the casters to make them roll if you wish. We like our design books in the Perfs with James the Bookend from Black & Blum supporting tomes in the few that aren't full.
