This set includes four sets of 10 cylinders varying in height and/or diameter in each set. Each set is in a separate wood box with the lid painted the same colour as the cylinders: red, green, yellow and blue.
This item is best for home use. If you are looking for this piece to be used in a school environment, we would recommend the Premium Quality Knobless Cylinders.
