New, Highly-Rated Product Materials: Leather, Aluminum How to Use: Upon arrival, the shoulder strap is straight. When using, gently bend it over your thigh to adjust it to the shape of your shoulder. Actual Usage Experience: It puts absolutely no strain on the neck and is very comfortable to use. Also, the length of the strap is easily adjustable, and the hook part has a safety structure, so there's no worry about dropping your precious instrument. I felt that this is undoubtedly the best product among the straps I've used so far. Although it takes a little effort to adjust the shoulder strap to fit at first, it's extremely comfortable to use once adjusted. Highly recommended product.
