Serengeti 5294R.
I think many people never heard of serengeti before.
This brands is very famous for the lenses.
Basically their collection's like ray ban classic line which is aviator,caravan kinds of styles.
Actually I've never seen this style serengeti before.
This is quite modern and hand stumped desolation where bridge and hinges part.
And also they use extra bridge and gold and silver 2 tones made these more stylish.
Frame is made in japan so high quality guarantee.
