comfortable writing

I am writing now a longer time with the gel refills Parker. These can be installed in most commercially available pens for large mines.
The typeface is very nice and even after prolonged writing the wrist is not overused because the gel refills not a big pressure when writing is necessary.
In offered double the Mines are cheap. Because each mine has a small protection to the core tip, which is easy to remove with the fingers, dry the second mine after opening the blister card is not enough.
