Ink leakage on the underside of the nib is not typical on the Lamy 2000; mostly the problem does not occur. It is recommended to turn directly to Lamy customer service in Heidelberg, which is predominantly judged positively. More common, on the other hand, are ink deposits at the tip, against which regular cleaning of the cap helps. On planes, the Lamy 2000 is unproblematically usable.
