Stylish purse.
Color: Black, Color: Black
I like the woven texture of this bag. The pin closure also caught my eye with its unique design. It can be worn for casual events and the shoulder straps can be removed to be worn as a clutch for evening. The material is durable and the black color seems bold and stylish. It is roomy inside and can hold my phone, lipgloss and some other items. This bag has a high end look at a great price.

I love how this clutch looks! The basket style design is appealing. I like how the closure is made, it's unique. I like the color. This clutch purse is not necessarily roomy, but it's enough space to carry my essentials plus more. Also, this clutch looks like genuine leather, I like that; and it's reasonably priced.
