Adjustable Mandrel Ballpoint Click Pen This is a set ofAdjustable Mandrels These mandrels feature a 7mm mandrel shaft that slides through a headstock collet. This feature guarantees a perfectly concentric pen. The mandrel easily adapts to different length projects.

The collet is tightened with two 7 8" wrenches (NOT included).
