The red handle was almost massive Aluminium. "Almost massive" means that the manufacturer bored an 8mm hole about 20mm deep on both sides. I took the freedom to extend one side to a depth of 40mm also using an 8mm drill (quite easy with Aluminium) and put my wrenches inside.

Now look what's inside: 4 different wrenches and 3 picks (or whatever you want).
The picks are mounted by tightening the screw, but I've also added some notches to the picks so they can't move when picking.

The label says "Mini Martor, Solingen, 26426". If you're interested, I found it on the web:

Or you may go and and find something similar by yourself.
