With this set of 8 different 3D puzzles you can build and create the Solar System in minature. The 3D puzzles are scaled to represent the different sizes of the planets, so Saturn and Jupiter are represented as 108 piece puzzles, Uranus and Neptune as 72 piece, Earth and Venus as 54 piece and Mars and Mercury as 27 piece puzzles, totalling 522 pieces in all. Each puzzle has curved, high quality plastic pieces, which are numbered on the inside for easy assembly. Each \'planet\' comes with its own stand and the whole set can either sit on the colourful \'Solar System poster (which includes facts about each of the planets), or be suspended by thread. The set also includes a kit which assembles into a \'sun\' mobile, and a fact-filled information leaflet for all budding astronomers out there! Suitable for ages 7+ Unique plastic pieces for a sturdy and strong model No glue required
