I handmade a drawstring bag using genuine leather! The size is perfect for a 500mL plastic bottle. It's perfect for holding a wallet and smartphone! The shoulder strap is removable. You can choose to wear it on your shoulder or hold it in your hand, depending on the situation. The lining is made of white cotton, making it easy to see what's inside. Please take a look at other colors as well! Because it is made from genuine leather, the color may differ slightly from the photos. Please view the photos as an image. I am a professional leather clothing manufacturer, and I am selling items I made as a hobby. Color: Black Pattern: Plain Shape: Pouch/Drawstring bag Material: Genuine leather
