Thank you for viewing! This is a horizontal sacoche bag. It has a simple design with a mysterious, kaleidoscope-like pattern. Perfect for casual outings, for a quick trip out. It can hold a long wallet, smartphone, handkerchief, tissues, key case, and more. It's a lightweight and convenient accessory, making you feel like you can "easily go out!" I hope it can be useful for you. It's also great for dog walks. I hope you can use it easily. Size details are shown in the photos. Please understand that this is handmade by an amateur, so it may not be perfect.
