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.
