I purchased this waist pouch online. The belt is made of elastic, making it very easy to use. It has a sweat-resistant function. I've been using it for about six months. It can hold the bare minimum: cards, cash, a smartphone, and essential medication. Perfect for travel abroad or for minimalists! Size: 22 x 13 cm Specifications: The front pocket has a divider that can hold two cards vertically. The back has a mesh pocket. The inside has a divider that can hold three cards vertically.
