Stylish and Functional, But with a Minor Quirk
Color: Brown Pu 239
I really love this PU leather backpack purse! It’s a perfect mix of style and practicality, but there’s one small design issue that keeps it from being perfect.
**Pros:**
- **Stylish Design:** The leather finish looks chic and goes well with any outfit. It’s versatile enough for casual outings or work.
- **Spacious and Organized:** The compartments are thoughtfully designed, with plenty of space for all my essentials without feeling bulky.
- **Comfortable to Wear:** The adjustable straps make it easy to carry as a backpack, and the weight distribution is great.
- **Durable Material:** The PU leather feels high-quality and holds up well to daily use.
**Cons:**
- **Top Handles Issue:** The top handles stand straight up when I wear it as a backpack, which can look a little awkward and get in the way. It’s not a dealbreaker, but I wish they could lay flat.
Overall, this backpack purse is a fantastic buy, especially for the price. If the top handle design doesn’t bother you, it’s an excellent addition to your wardrobe. Stylish, functional, and durable!

Stylish laptop backpack
Color: Black239pu
Chic backpack that holds a suprising amount of stuff. I needed a nice looking backpack for my laptop (Macbook Air 13") and accessories. It's sleek looking for work conferences and the top handles allow you to hold like a purse. I know some reviewers don't like the look, but for me, I like this feature. I have the black one and it has a nice quilted leather look. The straps have good padding and I was comfortable traveling all day. Even after walking several blocks in the rain there was no damage and everything inside stayed dry. The zipper and hardware are a good quality.

Perfect lightweight computer bag!
Color: Khaki239
Awesome lightweight bag. Very cute. Seems durable and well-made at a very good price. Has a ton of well placed pockets that keep me organized. I purchased this as a replacement for a much heavier, computer bag and this absolutely does the trick. It looked a little small when I received it, but it holds everything that I need and more. I have a 15.6 inch laptop. I highly recommend.
