I’m looking for a very small, maybe 3″ by 1.5-2″ pouch that’s reasonably durable (eg. woven nylon, canvas) for a storing a few small tools. I just need to put a couple small allen wrenches and sockets it in. Maybe two or three of each.

It needs to be flexible fabric (vs hard plastic) so it can go into a slightly bigger canvas pouch with other tools easily and compact. $10 limit.

TL;DR separate the little tools from the big tools and keep them all in the same pictured bag:

EDIT: This is almost perfect, just a little too big at 4.5″ x 3″ x 1″:
