Many pens require a NECKED SAC to enable maximum ink take up when the filling mechanism is the PRESS BUTTON method.
There are a few lever fill pens that require a NECKED sac, but the majority are button fill.
These sac's are made in the traditional way, by dipping the former into liquid latex.
The following sizes are available.
Please use the drop down menu to order you required size.
Detailed below each size are pens that take a NECKED SAC. There will be more than those listed but I have not found them in my research so far.
Any information relating to other models that take these NECKED sacs is greatly appreciated and will be added to the lists.
