Thay absolutely would be for something like that. As I said, I have one for my wrenches, and when you need to keep multiple things together like that they are awesome.
When I bought my wrenches it was two different sets- one metric and one Imperial (SAE) set and they came in plastic carriers (something like below) that were good enough but had a habit of belching out all of the wrenches when bumped, dropped etc.
I wanted something better but that still allowed them to be organized so that I would know if any were missing, so I got a wrench roll and it is the ultimate for convenience and organisation.
