Would be great if it was $10
Color: Gold
Feels like cardboard. I had one of these years ago .. but this style is hard to find. The quality is cheap. Not worth the price.

even nicer than I expected
Color: Gold
Perfect! Looks much more expensive than it costs. Looks exactly like the photos and feels just like it looks like it would. I absolutely love how spacious it is because most clutches can barely hold my phone let alone a pair of reading glasses and some lip balm. The color is absolutely gorgeous and exactly as it was shown. The zipper is quality the tassel is darling I love the fold over and a good strong magnetic clasp. The little shoulder chain is perfect whether you choose to use it or put it back in the bag.

Lovely
Color: Bronze
Very pretty clutch. I would really say this is a pretty large clutch. Soft! It comes with a metal chain, that I won't use. The tassel is a nice touch. This is not so formal that you couldn't wear it with jeans for a punch. I bought it with the Nine West Feather pump - bronze. They compliment so well! This is "cracked" and the shoes are not. But I'd still highly encourage pairing them. You could use this for a formal or create a smashing jeans outfit. Either way, just beautiful.
