professional: This original neck strap features a V-shaped copper plate with a playful heart-shaped hole. The beautiful design features a deep color of the smoked finish on the copper V-plate surface, a Gottsu engraving, and the shine of the SV950 silver hook. It features a soft, warm tone and the clear resonance that only silver can provide. This is an original Gotts neck strap that reduces strain on the neck and increases playing comfort. ----- The sound changes with the neck strap! That's right. The sound and playing feel change dramatically. The hook part has an exquisite gap to prevent it from coming off easily. Gottsu has returned to the origins of straps, meticulously crafting each and every part, and handcrafting them to perfection. The neck strap is made of genuine leather, carefully selected by Gottsu himself. The leather's softness and exquisite elasticity mean that there's virtually no strain on the neck. The simple, antique design, with the Gottsu branding, is striking. Gottsu has created a strap that's simple, yet lightweight, durable, and functional, a cut above the rest. *The vinyl tube on the hook is attached for protection. If not required, please remove it before use. *When storing, move the plate all the way down (this may cause the string to twist).[Size Guide]・Short (51cm)...For people with thin necks and children ・Standard (55cm)...For people with standard neck thickness ・Long (59cm)...For people with thick necks *The length for each size is measured from the center of the leather to the hook when the plate is lowered all the way down and stretched taut.
