3 Vintage 1980s SHEAFFER Multi-color Rubberized Ballpoint Pens with Advertising

Description

Here we have 3 Vintage 1980s SHEAFFER Multi-color Rubberized Ballpoint Pens + Chrome with advertising printed on the barrels. These are retractable pens with push-button mechanisms.
There is one purple pen with pink trim advertising Westlaw; a dark navy (or charcoal?) pen with turquoise trim for Ben Franklin Stores; and a pink with gray trim pen for Inter-American Advertising of Miami.
These are used pens that are in very good condition but they need new ink refills. (They use the "K" ballpoint refill.)
The Ben Franklin pen has the SHEAFFER name on the clip but the others do not.
