These are high-quality, slotted headstock style acoustic guitar tuning pegs. They were originally on a Natasha brand guitar. They are clean with no rust or clouding♬ There were no issues with tuning stability, but fine adjustments were difficult, so I replaced them with GROVER tuners. The screw hole positions are slightly off, but I've included images of the GROVER tuners in the second picture, so please use them as a reference for approximate size. They will be shipped in a GROVER case.
