These fret wires were owned by my father, whose hobby was guitar making (purchased in the 1990s-2000s). I have cut and bent them to make them more affordable. Size: width: 2mm, Crown: 1mm, Tang: 1.55mm Set of 21. Stewmac wire is made of nickel and is a high-quality wire widely used by various manufacturers and repair shops in the US. Please use it for refretting or guitar crafting. Please also refer to the Stewmac website: https://www.stewmac.com/search/?q=fret%20wire Although unused, please consider purchasing after understanding that I have cut and radiused them, and that they are not new from the manufacturer. #handmade #handmade guitar #vintage guitar #martin #gibson #merrill #santacruz #rare wood #woodworking #wood #solid wood #guitar wood
