i'm really annoyed with psi, turned 10 (would have been 12 but i had 2 burst blanks) pens, pencils, and fountain pens yesterday. found out to my dismay that the bushings that worked with the pens, didn't work with the pencils. the fountain pens were ok, and so were the pens. i found out also to my dismay, that with the pens and pencils, you cannot go down to the brass, you have to shave and fit, and shave and fit, and shave and fit a tenon on the blank for the cap. needless to say, i presumed they were like all the other kits i used, and took it down to the brass. it turns out the tubes for the pencils are half a red cat hair smaller than the pen tubes. without these tenons, the center band does not fit at all, too big. i'm going to try to salvage what i can of the pens, but the fountain pens came out ok. but the way i was treated by thier customer service and tech people was unbelievable. i haven't been treated like that much of an idiot since the one time the wife was mad at me. after this, it will be a very, very, very cold day in hell, michigan (a real place!) before i order from those folks again.
