The innovative modular Rocket Tower and Rocket Wall set from Manzanita Kids is appealing to kids of all ages and offers endless possibilities for imaginative play. Every wall-like flat block is notched at both ends, so that it can lock in with the other walls. Included in the set are two ladders kids can set up where they choose, allowing alien or astronaut toys to move about their base. Once built, the tower is large enough to house multiple sizes of dolls and figures since each piece may be easily adjusted. The entire set is made with a high grade 3/8″ birch plywood, an eco-friendly, durable material and has no toxic finishes. The Rocket Tower ships right to you in recyclable packing material.
