Review on Foamnasium 1023 Tunnel Red Yellow by Joe Glass

I received all 3 for the set. I would like this set to come with industrial grade double sided velcro to hold the pieces together. But my grandchildren love it. I had to buy velcro separately to keep everything in place. But the kids love it. I turned the tunnel upside down like a bridge. Looks good but very expensive for such a small size. Are some levels higher than others? Strange. But 4 out of 5 stars.
