This smooth-writing ballpoint refill can be used for the Retro 1951 Tornado collection (all models EXCEPT Elite and Fountain pens). Most Tornado pens come equipped with a rollerball refill (Retro item# REF5P), but you can easily convert your Tornado to a ballpoint with the Easy Flow. Manufactured in Germany, these refills are engineered with the finest cutting edge ink technology. They are sold in a 3 pack.

This is the Parker-shape refill, so this can be substituted wherever a ballpoint  Parker-style refill is required.
