This is a really cute and somewhat punky crossbody bag from the South Korean brand "Coming Step". The bag is 100% leather (lamb leather, dyed black) and has 4 pockets, including 1 zip pocket on the back, 1 zip pocket inside, and 2 card-slot pockets inside. Both the pockets and the bag itself are lined with black grosgrain fabric. The strap is a silver chain that clips on to the bag with lobster clasps and thus can be completely detached. You can customize the strap length by tying the chain in a knot. Unlike other chain straps, this one isn't very thick, so it's not heavy. This is a very small bag (6.5 inches wide X 4 inches tall X 1 inch thick) that's designed to just carry your essentials. NOTE: It will likely not fully hold your phone. You can stand your phone vertically inside the bag, but then it won't zip closed. It's perfect for holding your keys, ID, credit card, and lip balm. This bag was bought several years ago, but never used, and kept in cold storage, so is in new condition. It comes with a soft, drawstring dust bag that has "Coming Step" written on it. There's also a name logo charm on the strap. "Coming Step" is a boutique brand that is sold only in high-end department stores in South Korea.
