As trivial as they are, these brass rivets can prove to be crucial while making your own leathercraft, armour, hardware accessories, etc. These small MUSHROOM HEAD RIVETS are made from PURE SOLID BRASS, making them highly robust and hard-wearing. The length of each rivet pin (not including the head) measures approx. 5 mm (0.5 cm). These rivets come in a utilitarian set of 25 pieces.
