Keishi's Concho Screw Set (3 Pieces)

These are Keishi's concho screws. There are two, approximately 5mm and approximately 4mm.
I found them unnecessary because I switched everything to flathead screws out of convenience.
The 4mm is for thin leather that isn't layered. I believe it was originally attached to a key case.
The 5mm was used for the silver coin concho. I took it from my stored items when I obtained flathead screws.
These are for those who prefer the troublesome hex heads or want to complete their set with genuine parts.

I cleaned them, but there might be some screw lock agent or verdigris on the screw threads.
