Need help Identifying Piece

[Tatcha]

Found this in the Llano Uplift region of Central Texas yesterday Any help as to what this thing is would be greatly appreciated. It looks like something to clean a firearm but I don’t know. Piece opens and there is tiny brush inside. Looked under a microscope, found no markings or numbers on it. Thank you.

What about a sidearm? Would the cleaning kit tools be smaller?

I dont believe it has been mentioned but I thought maybe nipple cleaner for black powder rifle or pistol but not sure the brush is small enough. A nipple opening is like 1/16". Is the brush that small? The new pictures are very helpful. Cant quite see the loop but I can see the brush better and I agree it doesn't look as if anything is missing. There is a way to test if its nylon (modern) or something else by the way it burns or melts but I dont know if I would remove any hairs to test unless one happened to fall off.

Deffinatly looks like it might be a flash hole cleaner.

no where near big enough to clean my flash hole .

What about a nipple cleaner? or to clean under the nipple?

Maybe Im wrong. Maybe it could be a small powder measure like TxDetex suggested. I wish I had mine here to compare the size.
