I'm selling these because I have extras. ※The images are samples. The finish of the gear cover, the shape of the box, the number of washers, the color and length of the button screws, the shape of the bushings, etc. may vary depending on the lot. Although these are unused, they are outlet items and may have scratches, dullness, rust, chips, peeling, paint lifting, uneven finishes, etc. due to transportation and storage. Please do not purchase if you are looking for a pristine item. Please understand that these are not perfect like Gotoh products, as they are inexpensive. If you are looking for durability, quality, and reliability, there is a world of difference, so please choose domestic Gotoh products. Gotoh products have excellent precision, texture, and the overall construction, including the number of washers, is completely different, resulting in a wonderful feel. While they don't have the perfect feel of Gotoh, they are stable after tuning, which is part of the specifications. I find them useful because they are inexpensive and reasonably functional. Screws are included. I think they can be used for both acoustic and electric guitars. 【Handling Precautions for Tuning Machines, Tuning Machine Buttons, etc.】 ●Handle with care during installation to avoid damage. (Please be careful when tightening the mounting screws. Tightening them too much may cause damage. Also, align the screw threads of the mounting screws with the threads of the shaft before tightening. Tightening them when the threads are not properly engaged may damage the threads.) ●If the tuning machines are installed on a guitar with a headstock thickness of 1.7cm or more (or a guitar that is too thin), the nut may not engage properly, making installation impossible. However, this is due to the customer's circumstances, and returns are not accepted. (Please note that there are many cases where the headstock thickness varies, individual differences, and guitars with thick paint can increase the headstock thickness.) ●Also, the screw threads of the nuts, button screws, and mounting screws, as well as the screw heads, grooves, and resin buttons, are all delicate and not very strong, so they are easily damaged. Please handle them carefully during installation. ●Nuts with weak engagement may have shallow grooves and may come loose. In some cases, tighter nuts may engage more securely, so try installing them first even if they don't turn smoothly. (If you try to force a nut that doesn't turn smoothly to turn smoothly, the grooves may be worn down, making the engagement shallow and causing it to come loose.)
