Oh, and this, so your pen won't leak on your shirt, or anything else, after you fill it:

Fill it the regular way by dipping the point into the ink well and working your pen's fill mechanism. With my Montblancs and Pelikans, this is a rotating section at the end of the barrel that pushes a plunger inside the pen in and out. Out expels air and old ink, in sucks up new ink. Other brands of pens may work differently. The old Parkers, as I recall, had a thing inside the barrel that you had to squeeze, for instance.

With the pen still point-down, reverse step one so that you expel two or three drops of ink back into the ink bottle.

Now invert the pen and turn the mechanism to complete the filling process so that any residual ink on the nib is sucked into the reservoir.

There. You're done. Hope that's clear.
