This is a smartphone case that can be attached to the shoulder harness of a backpack. It uses cushioning and stretchy material, and can also be attached to a waist belt with the body's clip. I purchased it at a directly managed store in August 2023, but it didn't fit my backpack (BRIEFING URBAN GYM PACK), so I kept it unused. It is no longer listed in the catalog as of December 2025. I have kept the tag, so I will include it. 【Product Details】 ■Color: BK (Black) ■Material: 3mm thick foamed rubber [double-sided jersey] ■Weight: 50g ■Size: Height 16.5 x Width 8.5cm ■Compatible Smartphone Size: Height 15.8 x Width 7.8 x Thickness 0.7cm *It may not fit depending on the shape of the smartphone. ■Features: Back clip 【Shipping Method】 Yu-packet mini
