Vintage blue-gray buttons. Price is for 10 buttons. They measure exactly 0.8375" (a little less than 7/8" (21.3mm) in diameter. I am unsure if these are some type of US Navy button as they are the same size as the US GI M43 field jacket buttons (see comparison photo with an original OD button). New old stock and in good condition. They are not navy blue, they are more like a denim color.
