Message from fisher
The pen is pretty old so it has some damage from years of storage. However, there are no complications when writing.
Thin crack on both top (6mm long) and bottom (1cm long) parts of the pen near the threads (5th picture)
The threads for the bottom part comes off. It can come off if pulled while the pen is fully assembled. It’s up to you if you want to glue it.
