With 13 building tools and 6 two-ounce cans of non-toxic compound, this complete arts and crafts set empowers kids to build their skills and their imaginations with hands-on activities. Use the 5 cutters to make blocks in different shapes and stack them up in different ways. Try putting a roof on top with the roof stamper, or see if your tower gets more sturdy with the 3 flags. There are so many ways to build - how will your tower stack up?
