In trying to reclaim floor space in our son's bedroom, we bought this colorful cube composed of four stackable trays and a lid. Three of the trays have open grids of differing sizes, and together, they function as a phenomenal pickup, sorting (by size) and storage solution for Lego bricks. You just scoop the bricks up (our son has a dustpan that's dedicated just for Lego duty), dump them into the top tray and shake away. The smallest bricks sift down to the bottom level; each higher tray retains slightly larger bricks. At this point you can either further sort each tray by color and dump them into storage bins or just put on the lid. The cube itself is 10¼" on a side and purports to hold approximately 1500-1700 Lego bricks.

BOX4BLOX has been instrumental for well over a year now in keeping our son's collection of several thousand Lego bricks in some semblance of order and reasonably clear of his bedroom floor. So we sent one to our nephew for Christmas last year. In my son's eyes, as well as mine, BOX4BLOX really is a transformative tool— one that elevates a dreary task into something that's actually fun to do (and done well).
