This is a cow bone saddle, the same size as the Yamaha WT83730E. I'm offering some of the ones I bought for my Yamaha guitar, as they were well-received. Size: Approximately 75mm long, 3mm thick, 9.7mm high Material: Cow bone, unbleached It has almost the same shape as the Yamaha 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 are the perfect size for Yamaha guitars, so please take advantage of this! Price is for two saddles. Price is not negotiable. I am also listing a set of four, so please take a look. I plan to be closed from December 25th to 27th, so I will not be able to ship during that time. If you would like to use it during the New Year's holiday, please order early.
