This is an aftermarket product imported from overseas. It is a replica that reproduces the label sticker attached inside the soundhole of a Gibson acoustic guitar. It was created by a British luthier for repairs and has been used worldwide for over 20 years. Although it is not genuine, I think the size, color, etc. are well-made. Please refer to the images for the size. Please peel off the backing sheet and apply only the orange label. We are unable to provide support or answer questions regarding other installation procedures.
