Backpack Shoulder Slip Prevention Belt - Black, Set of 3 Total Length: Approximately 70cm Belt Width: Approximately 2.0cm Buckle Width: Approximately 2.8cm Weight: Approximately 19.1g Seiwa Pro Co., Ltd. Purchased November 2025 This chest belt easily attaches to the shoulder straps of your backpack. It can be fastened and unfastened with one touch. Suitable for various body types, from small children to tall adults. The black color complements any backpack color or age. The belt is about 2cm wide, making it very lightweight. It sits comfortably on the décolletage and doesn't dig into the upper chest. This is a convenient product that solves everyday problems for those who have sloping shoulders and find their straps slipping, those who tend to hunch or roll their shoulders inward to prevent slipping, those with narrow shoulders, those who walk, run, or turn around while wearing their backpack, those who want a stable carry, and those who want to stretch their shoulder blades by rotating their shoulders while wearing their backpack. Features: Attaches to the shoulder straps of backpacks, etc., to maintain stability while walking, etc. Prevents the shoulder straps from spreading and allows for comfortable carrying without slipping off the shoulders. The belt length can be adjusted to fit your body shape, and it can be easily opened and closed with a buckle. How to Use: ① Wrap it around the shoulder straps of your backpack (the size/shape of the shoulder straps doesn't matter because you can freely adjust the size of the loop). ② Pass it through the fastener and secure it firmly. ③ Tighten the adjuster to secure the backpack. It will be stable if you fix it at the same line as your armpit. ④ If the remaining belt is long, cut it and glue the ends, or tuck it into the loop that the shoulder strap passes through for a neat look. *Please feel free to inquire in the comment section regarding quantity changes, combination changes with other products, etc. *Changing to anonymous shipping is available via Yu-Packet Post Mini for an additional 100 yen. #Black #Gray #Backpack #Rucksack #Daypack #Dayback #Bag #Back #Kaban #Bag #Randoseru #Kids #Children #Girls #Boys #Girls #Boys #Women #Men #Ladies #Mens #ConvenientGoods #Kanon_kanon #BulkSale
