Tiffany Blue microfiber piano key cover, measures approximately 48" in width x 6" in depth. The bottom right side of the key cover has an attractive music design logo. Made of durable microfiber instead of felt, a big advantage to this material is its ability to keep the keys clean, and that microfiber wont shed like felt--if youre taking the key cover on and off frequently. Use to protect your 88 note piano or keyboard from dirt, dust and dampness.
