YOU MUST BUY!!
Color: Green, Color: Green
Hello, This is the first ever review that I’ve ever written. I couldn’t wait for this bag to arrive, and it came today as scheduled. It IS THE MOST - ABSOLUTELY BEAUTIFUL - as soon as I opened the packaging I could smell the leather! - the “colour” lol is RICH! I am a GREEN everything person, and this green is STUNNING! The QUALITY is great and appears to be VERY DURABLE. The inside is EXTREMELY roomy and deep, which is good for me because I’m lazy about zipping my purse up. BUT the zipper glides with ease. It’s a medium weight purse, so be aware of what you’re putting in there lol Value wise, it’s definitely worth the money and it looks MUCH MORE EXPENSIVE than it actually costs! I took the strap through and made it a shoulder strap also. I WILL definitely be buying the burgundy one next! Thank You ISWEE BOBBETTE

Great Tote Bag
Color: Navy Blue
This a really nice bag! I can't wait to go on my trip. It is just the right size, not too big, not too small. It holds a lot of things and I can reach in and see all of it. I like that it has the shoulder strap that you can either keep on or take off. The leather is so soft and looks beautiful. Seems to be really well made and I will have it for a long time and plan on using it every time we travel.

Very beautiful leather purse!
Color: Brown
I finally found THE purse that is perfect in every way. I love everything about it. It is a perfect size for me. Not too big and bulky and not too small. A medium size that holds a lot of stuff. It has double zippers on top which I really like. Comes in a dust bag, Crossbody strap is included. You can adjust the top handles to be shorter or longer. This bag is so nice, lightweight, a beautiful rich color, it is well made and smells wonderful.
