How to connect the disposable ink cartridges to a Parker Pen?
I need to know which side of the cartridge is supposed to be transferred.
The end that tapers in, with a small ball to be dislodged by the drill itself. ….. Parker Parker Pens have special cartridges are longer than the standard chubby – not to get one of those in (sure you knew that already!)
