I have drive across my city trying to find a sheaffer bottle that doesnt have this, and i have not be succesfull, after open more than 7 bottles on different stores i have found the same floaty things in the bottle... so maybe this is normal.. is it? Since is the first time i use bottled ink.. i have to ask about it. another question, do Cartridges could have mold?? because it seems that is the only option i have if i want to use Sheaffer ink. (I dont enjoy Lamy ink the other brand i can get in here)
