Comes with a real battery clock inside! The pendulum swings and works fine once you remove the little plastic that blocks the battery and untie the pendulum so it can swing! So cool for your dollhouse wall!
It will come to you with magnets on back. You can remove them or use them to help you mount the clock on your dollhouse wall. There is also a little hole so it can be hung on a little nail (cut off a pin to use it for a small nail).
This clock is about 3" wide x 6" tall x 1.75" thick.
