A pair of simple and durable braces for your trousers. No buttons on your trousers for braces? Be a man, sew them on yourself. The higher the waist, the better these fit.

Elastic, adjustable, and cheap as hell. Who wouldn't want a pair or two of these? On a related note, the color shades and texture of the leather/fake leather parts vary a lot. Some are black, we even encountered blue, white, purple, and pale skin colored specimens. We haven't separated these, naturally. Just get a bunch!

Czech army surplus

Used but in very nice shape, many even unissued.
