The Pelican connection has evolved over time as a "standard". So when described is that the converter for "Standardfüllhalter" is appropriate, says that that it fits on Pelican Standard. For Parker and Lamy the converter in any case does not fit. For Pelican connections of converter basically fits, but it can - depending on the dimensions of the spring retainer - nevertheless cause problems. In a pelican Celebry the converter, for example does not fit, because the body is too wide.
When my converter I have also the problem that the ink "stuck", so do not want to follow the gravity, so when writing necessarily dropouts come and the ink must be back forward shaken / tapped. The problem occurs regardless of the ink and, for example with water. If anyone has a solution to this problem, I would appreciate a response.
