No he said "blue or black ink pens"... he's being precise not redundant. If someone said, "Please hand me that blue pen," do I give him the pen with blue ink or do I give him the pen made out of blue plastic?
But I'm being pedantic (and also leading with a conjunction) so don't take me seriously, either. [big grin with a wink]
You are not being pedantic, you’re being accurate. I failed to grasp the proper meaning of the sentence, and it was properly presented.
