“Ink pens?”
What else would you call them?
As I said, I was raised in Detroit and went to the Detroit Public Schools. My oldest sister had to buy her text books through at least one year of high school. (I think she graduated in '69.) After that, the district supplied them. They also supplied you with cheap paper and pencils. The paper deteriorated if you tried to erase anything and the erasers on the pencils were horrible. We always bought our own supplies and were not forced to do the communist pooling of resources.
