Thank you for viewing. I purchased this from the official website about two years ago and have kept it unused at home. Size: 7.8 x 10.5 cm Color: Black Thank you for your understanding. From the product description: This is a versatile case beautifully finished with welding technology, without using thread for sewing. It has a simple design with a card holder and a clear window. It comes with a metal ring that allows you to attach it to a bag or add a strap. The smart design makes it a great gift. It's an item that is useful for everyday use in town.
