This is a cow bone saddle of the same size as Yamaha's WT83730E. I shared some of the ones I purchased for my Yamaha guitar, and they were well-received, so I'm offering more. Size: Approximately 75mm long, 3mm thick, 9.7mm high Material: Cow bone, unbleached It has almost the same shape as Yamaha's WT83730E, so it can be used directly on guitars such as APX500III/APX1000/LL series, CPX1000, FS820, FG820, FG820-12, LS6 ARE, and FS-TA. In the third and fourth photos, the white one on top is the genuine Yamaha saddle (removed from a guitar), and the cream-colored one below is the cow bone saddle. It's difficult to find cow bone saddles that perfectly fit Yamaha guitars, so please give these a try! Price is for two saddles. Price negotiations are not possible. I am also listing a set of four, so please take a look.
