Knobless Cylinders 12/20/2010
Reviewed by A viewer from St. Louis, MO US
Cylinders themselves have worked wonderfully for my two young boys. We have had these for almost one year and after being knocked down many times, the paint still has not chipped. This items has worked well in our homeschool environment.
