The Good: If you’ve ever assembled a banker box or any other type of corrugated box these will be easy for you, no instructions required. Took me about 15 minutes to put them all together. As I assembling my toddler began playing with them. He stood on them, threw them, knocked them down, used other toys to knock them down, and jumped from one box to the next. He continued to solo play with them all for 45-50 minutes. I call it a win.The Bad: There are only four larger boxes. One of the boxes had splitting cardboard so that made that particular box less sturdy.Tips: Make sure the inside flaps are aligned and straight. If not, the box will bow giving it a more of a curved side and make stacking them frustrating for the youngster.Comparative for size: Small box = 1 lb butter, Med box = single frozen pizza box, Large box= shoe box
