I bought this particular jenna because I wanted a round tube and it came out exactly as I hoped. The "cubes" are the perfect size for fingers old and young, and the pack comes with a sturdy "template" to build the stack for each game, so you don't have to figure out how to line up the stack. The wood itself is of good quality and for those who are smart it can be stained and stained if you wish to paint the blocks if you wish to make them more personal and appealing to children.
