Here is a 25th Anniversary Pentel USA Lancelot roller ball. These roller ball pens were handled out to employees who attended the NOPA 1990 Cocktail Party. I believe the Lancelot was the replacement for the Excalibur. I do prefer the Excalibur but this one is nice. On the side of the pen it is engraved "Pentel Of America LTD, 1965-1990". Nice addition to the supply room collection. These type pens use the pentel RMJ8 refills.
