"If you prefer an inking different than you use, order your next ribbon in a lighter or heavier inking.  There is no extra charge."
How cool.  I think "Ivory" may have been lighter as again, I do not see any "Ivory" boxes online either.  It would seem most persons would go for the heavier print.
Manufactured by the Kee Lox Company for all your typewriter ribbon needs!
