This is 2 three shelf units that stack so youre better off ordering this item because its cheaper than buying them separately.

Sized to sit on shelves 12 deep.  Wish they made one for 16 deep shelves as well.

Assembly was easy.  Took less than 5 minutes.

As others have noted, only holds 3 Campbells Chunky Soup-sized cans deep.  It can hold wider cans like tomato cans - each shelf is height-adjustable.
