This is a popular item that is hard to come by, so it's first come, first served. I'm not very familiar with it, but it seems like it can be connected to the backpack I'm also selling. Please judge everything based on the images, read the description carefully, and only purchase if you understand and agree. Please refrain from purchasing if you are overly concerned about details. ▶BOUNDARY SUPPLY / Stasis Sling / Shoulder bag / A USA brand, [Boundary Supply], was born from the intention to create high-performance products through technological innovation.
