Rotring Core rollerball refills

[wrenrutt]

This is an excellent pen, but I need to know if there are any standard rollerball refills that are easier to find than the Rotring refill. Thanks for the feedback.

Go to a stationary/writing store. There are some really good refills that turn an average pen into a psuedo-high dollar pen.

In my case, Pelikan refills fit my Rotring Roller Ball (old knurled brass one ).
