Nino Bossi bags are made from tanned leather. These bags are a growing trend; a lot of knock-offs are trying to emulate the Nino Bossi's but they are made from inferior leather. Also if you want to differentiate between Nino Bossi and other hand bags just look inside. The Nino Bossi's will have a nice design on the interior (usually lavender flowers), this same design is inside the smaller pockets too. My favorite aspect of the Nino Bossi's is the zipper, usually I find I dislike the unaesthetic appeal of zippers on purses (anyone else get this? maybe I'm just weird!?), however they look very appealing on the Nino Bossi's because of their fantastic design.

It matches the seams and looks so cute, see what I mean?
I've had a Nino Bossi for quite sometime and must say its very durable.
Note to shoppers : Don't buy from ebags.com read the reviews. This place is bad, bad bad.
I prefer buying from E-boutiques but they are sometimes a little more expensive and have a much smaller selection. I suggest window browsing google images for the bag you like and try to match it on a certified e-boutique.
