There is a whole series of small puzzles, called Woodiks. All are mechanical with gears and other moving parts.
The SKULL is one of our seasonal puzzles. When you pull the lever on the back, the skulls bones move up and down as well as his jaw opens and closes! 14 pieces, no glue required, all materials included in the kit.
A great collectible and can also be hung up so could be a nice decoration for the fall holidays!
