This Nextpal headstock strap adapter is easy and secure to install, requiring no permanent modifications to your instrument. Made from durable full-grain leather, it slides easily under the strings behind the nut, providing a stable and reliable anchor point for your strap while protecting the instrument's delicate headstock finish from scratches or damage.
