If you are into military style, Kaweco AL Sport Explorer is the pen for you
There are only a few writing instruments which have been successful in the market for decades without big changes. One of them is of course the Kaweco Sport. The greenish khaki finish pairs very well with the black nib and black finial. The black PVD nib also gives the pen a bit of pencil-like feedback, giving you more control of your handwriting. I am very glad Kaweco makes this color available and I was able to acquire one from Drop.
