I had to order two of this exact narrow cart (the TESOIN brand) because a few shelves arrived cracked between my two orders. I then returned one damaged package even though both had technically arrived damaged. I wanted to keep it for a specific narrow space in the hallway.
I also linked to a similar narrow cart (Chris W brand) I have for organizing Ralphie's grooming things.
The exact air tight containers are linked (from The Container Store).
