Not how I want to store my tools that are going to be USED. OK for long term storage.
Putting larger tools in these or similar containers would be hard because the tools don't really fit. A circular saw or wormdrive would fit the biggest bottom container in this stack. But then would you pile lots of little stuff around it and bury it to fill up the box? And have to take all the little stuff out when you want to use the saw.
And all of these boxes are accessible from the top. So everything in the box is on top of other stuff. Again, more digging to get what you want. At home all my small tools and accessories and supplies are stored in Craftsman tool chests with 4-5-6 drawers. Very few things are on top of others. Everything is accessible by opening one drawer.
These are different than the Festool containers because with Festool only one tool and some of its accessories are in each container. No mixing everything together. Everything is custom.
If you are USING your tools, drawers or shelves are the solution. Not boxes/containers to pile everything in together. Boxes like this are OK for storage, not usage.
