If you are looking for a bargain on a Parker Duofold Senior pencil, please take a closer look. Nearly 100 years old, this orange permanite beast is still working well. Twist the tail cap to advance and retract its 1.1mm lead. Click the headline to see easily that it is more than a little flawed. The pencil got dropped years ago on its twist top crown, denting it down on one side. Plus, its permanite outer shell has a bad crack under the pocket clip. 14.1cm.
