I bought this new on Rakuten for 2200 yen, but it doesn't fit well on my commuting backpack, so I'm selling it. This smartphone pouch can be attached to the backpack straps of backpacks and 3-way bags. It can be attached to the strap, allowing you to add a smartphone holder to your bag. It can hold smartphones up to 6.5 inches.
