Perfect for organizing spices.  My husband  I love to cook,  we have a lot of spices which occupied most of 1 cabinet.  This is the perfect solution - frees up a cabinet.  We installed spice rack in a kitchen closet right on the door.  It works perfectly for us.  We open the closet, all the spices are there on the back of the closet door, labels easily readable  reachable.  Such a winner.
