Cute but Too Hard & Noisy
Color: Nude
I was hoping this would be a little softer, but it’s definitely a hard shell. It is cute, but I don’t think I’d want to take it out much. It also makes a pretty loud noise when you set it down, which is a bit off-putting. Overall, just okay for me.

Great value for the money with a leveled up intentional design
Color: Black, Color: Black
This clutch is more stylish and elevated than I expected when I ordered it. The overall shape and that wave-like exterior give it a more interesting, elegant look in hand.
It comes with a gold chain strap, which is honestly pretty cheap and shiny, but it’s detachable, so you’re not stuck with it. Given the weight and width of the bag, I actually think using a chain makes sense — it’s not the easiest thing to hold comfortably as a clutch for long periods. If I were going to use it regularly, I’d probably swap the chain out for something a little higher quality.
The clasp is a gold flower with a small decorative jewel in the center, which adds a bit of personality and makes it feel less generic. That said, the hinge along the bottom is fully visible and would look more refined if it were finished in black or gold instead of standing out.
Inside, it’s lined with a satin-like nylon material. There’s elastic on both sides that helps pull the clutch closed, which is a practical detail. It fits a large phone easily, along with the usual evening essentials.
It is heavier than expected because of the metal frame, and the exterior is PU (vegan leather), so you get that structured feel. The size is also a bit larger than I anticipated.
One thing to note — it doesn’t come with a dust bag or protective cover, and the surface could easily show marks if you’re not careful, so you’ll want to store it thoughtfully.
The brand name (CHUNLI) is a bit different, but the design itself does a good job of elevating above that. It’s not perfect — the chain and hinge could be improved — but visually it’s interesting and feels more elevated than the price would suggest.

Excellent Party Purse
Color: Nude, Color: Nude
This is my new favorite clutch. I bought it in Nude and it looks so elegant. As can be seen in the pictures, it is very spacious. I was able to fit a phone, a small wallet and some cosmetics without any issues, and there is still room for more. I also had no issues with the open/close mechanism, which tends to be a problem with some other brands. The chain strap is removable making it a versatile piece. The chain is not adjustable. The exterior material quality as well as the inner lining seems sturdy.
The only thing I was not thrilled about is the gold color of the chain and the hook. I wish it was a milder tone of gold or even rose gold. Not taking any star off since it matches the listing.

Beautiful gold hard shell clutch
Color: Gold, Color: Gold
I love this elegant hard-shell gold clutch. It comes with a chain that is easy to clip on if you prefer to wear it as a purse. It fits my phone, keys, and cards (or a small thin wallet) and even has an inside pocket. The push-to-open flower clip on top is beautiful and makes it very easy to access. The flower detail is stunning and adds a touch of glamour. This clutch is perfect for any formal night or even a casual date night.
