Be sure to add me to your favorites list Yamaha Dust Cloth Mitten Wearable Type Cleaning Cloth for Pianos, Organs, and Electronic Keyboards, Used by Still Useable. This is a used soft dust cloth, which is worn as a mitten, for use for dusting pianos, organs, and electronic keyboards. It specifically says that it's best used with the polished wood of pianos, but I've used one just like it on other instruments as well, electronic keyboards and guitars for instance. You insert your hand into it, making it really easy to direct it exactly where you wanted to dust. It is 7 1/2 inches long and 6 inches wide at it's widest point. This has been used, with staining from previous use, but still has lots of life in it. It was made by Yamaha in Japan! THANKS FOR LOOKING AND CHECK OUT MY STORE!
