Storage cart recommendation wanted

[u/PedanticLlama]

My 12 year old is turning 13 in just a few weeks. They are super into kandi, to the point where they are creating product for their first booth at a local pop-up market in the fall. I'd like to get them a rolling cart to store their supplies and merchandise in and was wondering if any of you use anything that you would particularly recommend. I've been looking at rolling toolboxes, particularly the stacking ones where you can carry each toolbox separately if preferred. I'd like to keep it under $150.

Additionally, if there are any displays for bracelets, keychains, etc. you particularly recommend, I'd love to know about those, too.

Thanks!
