Nice, Smell Dissipated
Color: Sorrel
Update: I sat my purse out on the table with it opened. The smell dissipated enough so that I'll keep the purse. As I said earlier I really like this purse. It's well made and worth every penny. I'm giving it 4 stars only because of the initial smell. I love this purse. It is indeed genuine leather. However, it smells horrible!!!!!!! I am letting it sit out and if the smell doesn't dissipate I will return it. The smell is so bad it makes the purse unusable. I really like this purse so I hope the smell improves.

Stunning and Functional
Color: Light Blue
I purchased the Light Blue handbag to accompany some turquoise blue shoes. I had to return the shoes because they were too small. Yet, I am keeping this handbag. It is absolutely gorgeous! The braided accent across the handle is a beautiful addition! The bag measures 12 inches long, seven inches in height and four inches wide. There are two zip compartments inside and two pouches for your phone or keys. The bag is roomy enough for my essentials: wallet, small cosmetic bag, phone and keys. It comes with a leather strap so that you can use it as a crossbody. This purse is definitely leather! I have bought enough polyurethane to know the difference! For the price point of $69.99, this purse is a keeper!

Lovely bag
Color: Black
I really love this bag! The size, color, texture & easy access is perfect but it has a bad smell! I’m not sure I can explain the smell! It’s a petroleum chemical smell I hung it up in hopes of airing it out. If that doesn’t work I’ll have to return it. I hope it works for the bag is perfect otherwise!!!

Beautiful, Roomie, Love it!!
Color: Sorrel
Very nice leather handbag and also has a long strap that comes with it so you can use as a crossbow if you would like too. I really love this handbag ,I might buy another one for fall. Just bought this one thru the winter. Know I just bought a new blue bag for Summer. I love my bags! But this bag is made really well. It will hold up for quite some time and it is pretty roomier inside.

Good quality and stylish also. Great purchase.
Color: Wine
This purse arrived timely and without damage. Product was well secured to prevent tears, etc. This purse is exactly what I was wanting. I was needing a purse that a more rectangle shape allowing me to access more easily with my arthritic hands. The leather and workmanship of this purse is very satisfactory. There are several compartments inside, some of which have zippered closures which allows added security. The color I chose is a rich wine red. I am more than pleased with this purse and will purchase again later in other colors.
