PRS Rollerball adapter - Bock 250

Our rollerball adapter converts your fountain pen to a rollerball by simply threading this into the section in place of a Bock 250 nib unit. Compatible with any pen that uses a Bock 250 nib unit. Internally, this uses a Schmidt PRS rollerball tip, which allows you to use your favorite ink in a cartridge or converter, with a rollerball tip! And yes, a converter can actually pull ink in through the rollerball tip!

The Schmidt PRS rollerball tip is designed to be used with the Schmidt k5 converter and international size cartridges, and may not be compatible with all converter styles.

Includes a Schmidt PRS rollerball unit, and a Bock 250 adapter sleeve.
