String bushings for string-through guitars. Can also be used for the top side of the body of string-through guitars. These are special-shaped bushings that are rarely sold as parts. Unused, black-plated. Please refer to the dimensions in image 4 for size and use them for repairs or custom parts. Please note that the dimensions are measured by me with calipers, and there may be some errors due to variations in product precision. A set of 6 will be sold at a bargain price. Immediate purchase is OK without comments. Please note that this item will be shipped by regular mail, and according to Japan Post regulations, there is no arrival guarantee or compensation for damage. Please understand this before purchasing. Also, I am sorry, but I cannot accept price negotiations.
