i just need to find a good small bit set to go with it

I actually had previously already gotten this cheap set just to cut through the soft rubber and sliver off a small set-holder for myself. (just a bonus that the bits will all also work for anti-tampering cases, like one of my leathermans).

I cut a long row out of the top/green half of the container, leave the rest at home, and I filled the cut-off row with what I need for a bike (for my bike: 3, 4, 5mm hex) and some basics (a couple phillips/flat-heads).
