These fret wires were owned by my father, whose hobby was guitar making (purchased from stewmac in the 1990s-2000s). I have cut and bent them to make them more affordable. Size: width: 2.45mm, Crown: 1.45mm, Tang: 1.2mm Set of 21. Stewmac wires are made of nickel and are high-quality wires widely used by various manufacturers and repair shops in the United States. Please use them 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 radius-ed them, and that they are not brand new from the manufacturer. #handmade #handmadeguitar #vintageguitar #martin #gibson #merrill #santacruz #rarefwood #woodworking #wood #solidwood #guitarwood
