Thank you for your interest in this product. ＜Product Description＞ This is a set of 6 Gotoh tuners. The box says "SG381-HAPM," but as I received it from someone else, I'm not sure if the contents match the box. Also, I have never used it myself, so the operation is also unconfirmed. Bushings, washers, instructions, hex wrench, and screws are included. Please purchase only if you can judge the item from the photos. #GOTOH #Guitar #Tuners #Gotoh
