Original WWII production size 27 Ligne (just under 3/4") khaki buttons. These are used on all manner of trousers including wool, khaki, and M42 paratrooper and occasionally on jackets.

Color is "OD" which, in this case, equates to something resembling caramel. They're original so the color cannot be incorrect.
Price is for 1 button.

Note! There are several very subtle variations among these due to being made by multiple manufacturers. We acquired them in the original boxes and they were packed by the gross like this. All are brand new and un-used.
