These are high-quality, slotted headstock style tuning pegs for acoustic guitars. They were originally on a guitar from the brand Natasha. 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 for a general size reference. They will be shipped in a GROVER case.
