It's a party to make this puzzle! Because the puzzle has the contours of a rocket, and is not straight on, it is extra challenging to get all 300 pieces in the right place. And once the puzzle is finished there is so much to see, one to frame and hang on the wall ;) The puzzle is made of 90% recycled cardboard and printed with natural ink (non-toxic). A super cool gift for children from the age of seven.
