Pentel hybrid TECHNICA KN104 hybrid TECHNICA KN103 hybrid K177 ROLLY BP110 These are old models, seemingly discontinued. They currently write (some may be scratchy), but I cannot guarantee their condition. There appears to be air bubbles in the black ink. I also detect a slight old smell. I received these from an acquaintance, and I have no expertise. I hope those who can judge from the photos will consider them.
