Take your favorite bottled fountain pen ink with you and fill up your pens on the go with the Pineider Pen Filler. Compatible with most filling systems, simply insert the nib and section into the opening of the container, make sure the fit is tight and it's locked in place, flip it upside down, and refill!
The filler vial holds a maximum of 10ml of ink. It is compatible with grips that measure 9.5mm to 13.5mm in diameter. The box has a handy size guide on one of panels, so you can measure your pens before you try to fill them.
