These fret wires were owned by my father, whose hobby was guitar making (purchased between the 1990s and 2000s). I have cut and bent them to make them more affordable. Size: width: 2mm, Crown: 1mm, Tang: 1.55mm This is a set of 21. Multiple sets are available. Please inquire in the comments. The 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 brand new from the manufacturer. #handmade #handmade guitar #vintage guitar #Martin #Gibson #Merrill #Santa Cruz #rare wood #woodworking #wood #solid wood #guitar wood
