I recently went on a cleaning/organizational spree and these cubes were a key player!  I purchased 2 sets of 6  (12 cubes total) and will likely order more.  I've sorted and contained Everything …..from toys, to pantry items, to linens.  There's something about looking at a shelf with neatly ordered cubes that eases tension.  There might be chaos waiting inside the cube … but you don't see it and it doesn't drive you nuts!
