It's so  lovely !You could put the coin in it one by one,at the same time.it could sing the song,If you want to open it,please turn it left .If  you want to take the clouse ,please turn it right,

Please do not open it with  the opposite direction ,That will damage the tank music money, Please follow the instructions to use.It's easy!

That's  easy to use, simple to operate,and make it as decorations or display, children are a good partner!!!
