Pencil Mechanism | For use with TM ballpoint kits
The TM Pencil mechanism replaces the spring and refill in the TM ballpoint kits. This mechanism works with both twist and click pens.
How to use with twist kits:
A twist clockwise moves the lead down (and allows you to push the lead back in)
A twist anticlockwise then locks the lead in place.
(Not compatible with TM Delta or BMPK Pratchett
