This is a non-sale NPS strap. I have used it, but there is no noticeable damage. * A rare NPS strap that Nikon distributed only to professional photographers. * Not available for general sale. It is a professional specification, so it is well-made and has an elegant design. Especially recommended for Nikon users and collectors. * Excellent durability. Wide and sturdy nylon material, it will not dig into your shoulder even with a heavy SLR or telephoto lens, and you can use it comfortably. Also, the non-slip processing is ideal for long hours of shooting. Please consider this item, understanding that it is a used item. I am also selling another similar item. Set sales are available. I will discount it a little.
