Item may be delivered later than quoted. This is a fun whimsical clock for Christmas. It will play a different abbreviated Christmas song on the hour. It is new in the box. It measures approx. 11.5" in diameter. I tested it and it works great. It does include the instruction sheet. If the songs do not match up to the hour, you simply use the reset button on the back to get to the correct song. Also the sensor detects light and if it is dark it will play quietly or not at all depending on how dark it is. You will need 3AA batteries to operate this. Please note the battery covers are not missing; this is how it was made. Also, I want to note that the front of the clock is GLASS, it is not plastic so be careful when handling. I think this would be a great gift for anyone who absolutely loves Christmas and loves to decorate. Also a great gift for an older adult.
