Metal buttons (17 mm diameter) with three holes for fastening. We offer steel and aluminum buttons, choose the material before order.
Buttons with three openings were used in the XXth centruty on German equipment (bags/Brotbeutel, tents/Zeltbahn, backpacks/Rücksack) and very rarely (at the end of the war for economic reasons) to complete the clothes. Three holes provide striking sustainability of buttons against tearing even when on dry or putrescent yarn. Such buttons may be found on battlefields with a torn bridge between the holes: i. e. button physically broke, and not come off.
The buttons were made of aluminium, zinc and steel. Very rare they might be bakelite (material based on resin and fillers), brown colour. Zinc buttons - the earliest, pre-war. Aluminum were produced before the war and up to 1940, then steel buttons began. Most often these were made of a very thin sheet of steel (about 0.3 mm), which was covered with a gray semi-matt paint (without galvanizing). The paint on the original buttons could cleave, and they rusted. We don't need saving, we do the steel buttons of 0.7 mm steel coat them with zinc for corrosion protection. For full compliance, you can cover them with gray paint by yourself.
