Great clutch
Color: Silver
Great clutch! It is just as pictured and a perfect size because it holds my phone, glasses and lipstick with room to spare. The straps that came with it are easy to remove and detach from the inside, which is great because it doesn’t have the rings or other attachments which most have that show.

What a nice surprise
Color: Black, Color: Black
This purse totally surprised me. It is so nice. It feels rich, soft but structured. Looks way more expensive. I love it.
Update. My only complaint after using is the magnet closure isn’t really strong so can open easily

Amazing bag
Color: Black
Omg this is seriously the cutest bag. I purchased the black so classy looking and I love that you can carry It 3 different way. It looks like an expensive bag. Can’t wait to use It at some weddings as a clutch and then a cross body or shoulder bag other days. . It has card slots in It which is so good when you don’t want to carry a wallet. I did put a small wallet my phone and lip gloss and keys and still have room.
