Vintage Pentech 1996 Coca-Cola Pen Case. The pen case was sold as a collectible gift item in the mid-1990s. It is a metal tin case shaped like a contour Coke bottle. The pen is included with a new pen refill (not the original). On the front of the tin case it reads: Coca-Cola - Trademark Registered - Bottle Pat'd Dec. 25, 1923. On the back of the pen case it has information about the Coca-Cola product and it all started in 1886. The case and pen are in excellent condition and looks like it was never used. Just needed to get a new refill. Please see the photos. If you have any questions, please let me know.
