I have been using the Molotow chrome pens for about four years now and I really like how they perform. But I do have a question about their longevity. Lately, I have noticed that both of the 1mm pens are no longer producing a chrome finish, more of a dull silver look, even after I have shaken the pens for quite some time. I know the chrome is still liquid as I can feel it when I shake the pen. One of the pens is about 3 years old and the other one is maybe 18 months old. I usually store the pens laying down on their sides, so that the chrome doesn't settle in the tip or bottom of the pen.
Is anyone else having the same problem with these pens? Is there a shelf life or storage problem? Any help would be appreciated. Thanks for looking.
