I needed something to stop my ¼" drive socket sets from rattling around in my tool bag. I had some old Altoids tins that were a pretty good size.
The trays snap into the tins just under the rolled metal lip. The sockets are held snug, but not so much so that they are hard to remove. I added a bit of felt tape to the lid to stop any metal on metal clanking. It took a few iterations to get the text clear for the SAE set, but I'm pretty happy with the result.
