Thanks for the details. Though I do believe Stalwart does not make them. There are several brands who I’ve seen use these same exact product. Stanley was the first to the market from what I saw, but who really knows. They all could be rebranded from some other brand.

These Stanley cases are good and you can move and take out the yellow bins https://www.amazon.com/Stanley-Tools-Consumer-Storage-014725R/dp/B074CDCVN8/ref=mp_s_a_1_3?dchild=1&keywords=stanley+organizer&qid=1612909702&sr=8-3
