Beautiful, sturdy and comfortable!
I am very satisfied with this bag! I honestly thought that because the price was so low that it would be more of a lightweight beach bag, however, it is very sturdy and holds so many things. The straps are very thick and comfortable. There are a few pockets inside zippered pockets of some side pockets and a front zipper pocket. I get so many compliments on this bag. Two of my friends actually bought the same bag! I honestly want to buy another one just in case somewhere down the road something ever happens to this one because I am obsessed with it. I use it every day for work is very easy to clean as well. It’s almost like a neoprene type of fabric so it wipes off very easily. I highly recommend this product.

Works great for me
Color: 06 - Black
I love the size of this purse. Not too big but big enough to hold what I need. The compartment for credits cards and drivers license works better than carrying a wallet. I'm really happy I purchased this. Works better than any designer bag and for a lots less money.
