We used these carts in our cosmetics manufacturing lab and no longer need them. We also have a few 2 shelf ones.
We are amidst moving so the pictures aren't great. There's one from the manufacture in there, and if you want any more pictures, or to confirm anything before coming by, send a message and we'll get back to you with them.
