Effective since 1950

With about two kilometers a pen, you can easily fill several hundred pages, so if you do not lose, you should not have too often buy such a package. The few predecessors in this package have all, for me, lasted at least six months. I favor fountain pens, BIC but are much more useful in everyday life, and I nai no qualms about exposing them to harsh environments seen their prices.

If I had a criticism to make, it would be Legard green of the ink which is rather pale, it remains readable, but it lacks contrast.
