I am making a mobile pocket for adults. This one is a waist pouch style. It's very easy for those who dislike shoulder straps, as it just attaches to your waist. Your hands are free, so you can use both, and since it attaches to your waist, your shoulders won't hurt and it won't get in the way. You can wear it over a jacket as shown in the photo, or use it as a belt around your waist. It serves as a focal point on your waist like a belt. Vintage canvas is heavier than regular canvas, so it provides extra security when carrying a heavy smartphone. This is a new color, beige, in vintage canvas. The height is 18cm, accommodating slightly larger smartphones. The sum of the height and width can be up to 16.5cm. If it's longer than that, please consult with us. Height 18cm, Width 13cm, Depth 2cm
