This is a small cylindrical mandrel. It is about 9 1/2 inches (24.5 cm) long and the diameter is a little less than 1/4 inch (6 mm).  It has some rust, but it is in good functional condition.

The shipping calculator sometimes charges too much. If it is over by more than a few dollars, I will give you a refund for shipping. Also, if you purchase more than one item, I will send them together to save you money.
