The well-made, fine knurling is also an attractive feature.
Please note that this is not a drafting ferrule.
The barrel is plastic with a resin coating.
This price is possible because this item is not discontinued but is still listed as a current item.
If it becomes discontinued in the future, the price may increase without notice.
