Shoulder strap and card holder set. - Red strap - Shoulder strap - Black card with tour logo This is a smartphone shoulder strap that was a bonus for the first purchase of the back number, anti sleeps tour 2024 live DVD. It's designed to be used by inserting the card part between your phone and its case. The red strap is eye-catching!! The length is also adjustable. I'm selling it because I don't have a chance to use it.
