Yamaha keyboard music rest/holder. It came with my E223 and I have never used it and never will. It is brand new. Although it comes with the E223 model I would bet it would fit other Yamaha keyboards so here's the important part. The stand measures 19 1/2 inches long and 8 1/2 inches tall  including the "feet". The "feet" or what fits into the keyboard are 2 1/2 inches long. The distance between the feet is 14 inches.

I will ship to the U.S. but will ship internationally. PLEASE contact me for a shipping quote if you are outside of the U.S.
