The K5 Schmidt converter is a high quality standard international long converter, made in Germany. While it is considered a standard international converter, check to see if it works with your fountain pen. We know that this doesn't work with Sailor, Sheaffer, LAMY, Pilot, Parker, etc.

You can use this converter safely with all our fountain pens except the Zebra G Fountain pens. Osprey Zebra G fountain pens work with Osprey custom Converter or a K6 Schmidt converter.
