Amazing alternative to pricier bags
Color: Black
This is a great bag! I wanted a high quality, real leather bag to carry as an alternative to my pricier luxury bags and this is perfect! The leather feels great, the stitching is meticulous, and the design is so classy. A+!

Perfect smaller bag for your shoulder
Color: Burgundy
This is a great little bag well made, and holds a cell phone, a wallet and a few other necessary items. The clasp is quality as is the strap. The only complaint is that the leather is very hard. I thought it would be softer. I have had many compliments on it. Some people saying it looked like a coach others thought it was another brand name. Definitely recommend if you don’t want to spend a lot of money and have some class hanging from your shoulder.

Cute night out bag
Color: Burgundy, Color: Burgundy
This bag is cute for a night out, I love the material and the color. It comes with two straps, one is a crossbody strap and other is shoulder strap. The shoulder strap is long enough and is perfect length. I foresee this bag the last for a while since the leather feels thick. If I had to change one thing it would be the hardware…. I would change it to real brass and this bag would be perfect in my eyes. I even purchased it in black after I got this one. It fits my thick compact wallet, my keys, my dijo pocket camera, lipstick and earphones comfortably.

Color and Material
Color: Coffee
Color is not as described; it is much lighter than the photos. It appears more like a toffee color, while I was hoping for a deeper brown shade. Additionally, the material does not feel like leather.
