Very nice but...
Color: B-brown
It's a beautiful bag but the outside zipper pockets are deceiving, they're very small . My phone couldn't fit inside. No bad smell, the organization inside is good and the strap length is pefect. Because the outside zipper pockets are too small I may have to return it.

Good quantity
Color: A-shiny Brown
Perfect size for me. The different compartments makes it easier for organizing.
Has a mild order but after turning it inside out and put it in the sun for a few minutes, problem solved.

It’s a YES from me!
Color: B-brown
I absolutely love this purse. And I’m so heartbroken because something got spilled inside of it and it affects the functionality of the person on the inside and it makes me so sad but I still use it anyway because there’s one side I can use completely and half a side I can use on the other side lol. It is very good quality. The storage is A+. It is definitely a good value for the price. I was skeptical at first as we all are ordering a purse off Amazon, that is not real leather, but it’s supposed to be good quality. It didn’t really have much of a smell. I actually don’t use the strap provided since I seen that the straps could be interchangeable, I used my strap off my previous purse instead, and now I love it love it! 😍 I get compliments on it all the time!
