Pair of top bronze cups, pair of bronze gobelets, ethnic bronze, patina of use, geometric patterns

Pair of bronze gobelets.
They were probably in North Africa or central Africa.
This is a rustic primitive style.
They were hand made with different patterns.
The one has lines this other geometric patterns in the shape of triangles.
They were hammered .
They show an important patina of use.
One of them is much darker than the other one.
I don't think they can be used anymore but they would be perfect decoratively speaking.
They would be perfect in an ethnic style decor.
They could also be used as small vases.
They could be perfectly mixed with minimalist or industrial style. top
