Screw-back buttons in a matte gold finish and a nautical design on top. They can be used to attach some styles of epaulettes: ones that aren't too thick (think fabric epaulettes, not braided ones) and that have grommets in the near-shoulder end to a jacket that the screw can be put through. The thickest material they can work with is about 1/2" (12-13mm). One size: 24 Line (16mm, 5/8").
