Get to know the technical world with the Elektro Maze Challenge building set. Build your own structure on the construction board or follow the instructions. When you touch the metal wire with the magic wand, something exciting will happen, including a flying saucer and a ringing bell! Because the Electronic Blocks sets can be combined with each other, there are endless possibilities (Cannot be combined with the colored electrical building sets). Battery operated. The manual of the set is in English but with clear and extensive images.
