Hi everyone! I recently got my first Delta Pen … I got lucky, and had the chance to get a Delta Unica pen in a very good condition, but … After I tried to draw out the nib, the grip section got loose and now I have a resin tube (formerly grip sectin) and the nibhousing with nib and feed. I do not see any rests of glue or something else, so I am thinking about, how to fix the grip to the nibhousing again, because, if I do not fix it, the grip section constantly turns around … Should I use a strong adhesive, to glue the resin tube to the nibhousing or should I just use kind of a schellack??! Perhaps, here are some Delta pros that might help … Best wishes and happy writing! Daniel
