Beautiful Large Purse
Color: Light Brown
5 STARS !! Love this purse. I have had expensive name brands and this I has been my favorite. Love the size, the hardware, the long strap, stong handles, the feet on the bottom the color is beautiful. Great quality so far 6 months. Even got sprinkled on in the rain dried no spots. The large is large so if you like large bags it is it. I have always wanted a I guess you would call it a medical bag. As you can tell from this I really love the bag

Great choice
Color: Light Brown
I probably lost a good 40 bags in a house fire and am just now able to begin to replace them. I made a good choice starting with Iswee! The quality and craftsmanship is top notch! Easy to get into and find items right away! The leather is soft and sturdy and the color is great! I would have rather the hardware be done in an antique finish rather than a shiny silver but it’s okay. I’m going to enjoy carrying this bag! Thank you

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.
