I traded a couple of PMs with Kim earlier today, mostly about Altoids containers. I picked up from a few of his responses that quite a few of us use them as swap boxes and as fly boxes on the stream.
I manage nearly all of my flies on the water in Altoids tins and I 3D print divider inserts that convert them into really functional fly boxes.

Kim agreed to let me send in a bunch with my fly offering and he'll distribute them out to you when he sends back flies.
I told him it was my apology for the really crappy flies I'm sending you 🙂
I hope you choose to snap them in and give them a try.
