We’ve upgraded our popular book bins to make them more functional than ever! Each one now includes a swing-out bottom stabilizer wing (patent-pending) that helps prevent the bin from falling over when full. The wings extend 1¾" on each side, but can be overlapped to save precious shelf space—just swing them back in to stack the bins for upright, compact storage. And each bin includes a built-in label holder with a clear, protective cover and colorful cardstock labels so you can easily identify contents.
