These are authentic buttons, or horse harness attachments, crafted by the Scythian empire in roughly 600-300 BCE!
These nomadic Iranian peoples were primarily based around the central Eurasian steppes and were among the first to master the art of mounted warfare!
This radical shift to combat via horseback gave them a significant tactical advantage over many of the armies they met in battle.
Price is per button and they can be shipped worldwide! These measure ~.65".
