This is a hand crank music box. The detail is the engraving is immaculate. Such a heartfelt gift!Got it for my dad for his birthday! He loved itwell, all I could do was laugh when this arrived. It was TINY, like smaller than a golf ball. I wasn't expecting it to be so small, but my father and grandfather both liked their gift.My grandfather absolutely loved this for Christmas, and he played it over and over again just so he could get the right rhythm. The top to the box is a bit loosely attached, but it still works just fine.
