These were owned by my father, who enjoyed making guitars in his lifetime. They are made of abalone shell, not laminate or celluloid-like materials. There are 20 pieces in a set, each approximately 20mm to 3mm in length, 1mm thick, and 1.5mm wide. Please forgive any errors, as I haven't measured each one individually. Please refrain from purchasing individual pieces. These are fragile. I will pack them carefully. #Inlay #Shell #AbaloneInlay #Handmade #HandmadeGuitar #VintageGuitar #Martin #Gibson #Merrill #SantaCruz #RareWood #Woodworking #Wood #SolidWood #GuitarWood
