Best 1:1 Leather Designer Backpacks?

Looking for a great 1:1 leather black backpack. After reading through many post it seems like the best option would be getting something from Fang/Anita/Darcy/Nina.

Looking for something not too flashy or too much colors. I really like the Apollo Fragment backpack that people have been posting I think from Nina, but it seems like that has some flaws.

Any other suggestions? Any price range would be fine. Thank you
