MUJI Water-Repellent Nylon Business Rucksack to Reduce Shoulder Burden Please check the condition in the photos. It will be folded and shipped. Please refrain from purchasing if you are overly concerned about details. --- [Patented Technology] MUJI's original shoulder straps reduce the burden on the shoulders. When carrying heavy luggage, the load on the shoulders is designed to be distributed across the entire width of the shoulder straps. This reduces the feeling of carrying a weight heavier than the actual load, and also reduces issues such as the shoulder straps digging into the shoulders and causing pain, resulting in the effect of "reducing the burden on the shoulders." Patent No. 6445744: Patent for backpack shoulder straps and a backpack equipped with them. This bag has an internal PC storage pocket. The fabric uses recycled nylon and is water-repellent treated.
