These subjects are more than 3000 years old. They were made by ancient masters in the Bronze Age. In those days, the masters could not clean the metal from the slag because of this they have such a look. Such items are very rare, every find is a huge success. How these items were used is not clear, it was probably just amulets. Thus, people wanted to attract luck to their side and protect themselves from evil spirits.
