Set of 6 SE700 machine heads with nickel finish and mounting screws. - Model: SE700 - Finish: Nickel - Button Type: SL - Accessories: Mounting screws - Quantity: Set of 6 I am selling these because I purchased silver and gold colors earlier this year and installed the gold ones on a guitar, so I don't think I'll be using these. They are new, but have been opened for arrival inspection and photography. I purchased these for a k.yairi guitar, but I think they can be installed on guitars with open peg or Kluson-type pegs. Please confirm the size yourself. Please understand that this item has been in someone's possession once. Thank you for looking.
