Cute and high quality
Color: Cream
I love this purse- I have it in cream and gold. It looks high quality and has held up well with lots of use. Big enough to fit a decent amount of things inside.

Absolutely beautiful!
Color: Brown, Color: Brown
I needed a purse for my brown/orange colors to use occasionally. I returned a black one from a different company but I loved the gold handle. I saw this and realized it was perfect! I like the shape of this handle and the texture/color better anyway. Not too big or small, beautiful color and the magnets are great. There’s a zipper compartment inside. The chain is pretty sturdy but it’s removable and you can attach a different handle/strap if you’d like I love the look as I’ve got two Brahmin bags . The texture prevents being to see any small scratches and you can just wipe it off with a damp cloth I’ll carry it with the chain inside but don’t know if I’ll use it. People complain about the quality but seriously? It’s a $30 bag! I think it’s a great value myself. It’s sturdy enough to keep looking very nice and functional for a long time.. If you’re looking for a small clutch, this isn’t it, but it’s not too big either. I love it !

BEAUTIFUL clutch purse! I would buy it again in a heartbeat.
Color: Green
The craftsmanship of the clutch purse is fabulous. The color is a bit darker green and not the obnoxious grass green color. The crocodile pattern is stylish and the finish is shiny and reflects light. The interior is cloth and has a spacious inner zippered compartment on one side. The zipper moves freely. There is an included shoulder chain which attaches on the inside of the clutch. My only negative issue is the plastic wrapping on top of the handles. The plastic was anchored UNDER the metal handles. This yielded some difficulty to get the torn parts of plastic out from under the handles. I only used my fingernails and was able to coax most of it out. I'm hesitant to use any kind of tool to get the remaining plastic film out. The shine on the outside of the bag makes most of the plastic bits unrecognizable. I got this clutch purse for Christmas time. It will hold my lip stick, wallet, keys, and phone just fine. I doubt it would hold much else. But I'm OK with that. I don't carry much stuff with me anyways.
