A friend of mine won an eBay auction that unexpectedly included a lot of nearly a dozen 1990s/early 2000s-era Sheaffer Preludes. These particular pens were apparently done as promotional gifts for ETS (Educational Testing Services) and has a small ETS logo on the clip. Each pen bears a medium stainless steel nib, and comes with a Sheaffer piston converter.

These are new old stock (NOS) pens that have not been used and are shipped in the original packaging.
