Pen and paper are traditional writing tools, but there are many synonyms that can be used to describe them. A few of the most common synonyms include writing utensils and stationery, which both refer to the tools used to write on paper. Notebook and notepad are also popular alternatives to paper, as they describe the place where writing is done rather than the writing surface itself. Other options might include quill and parchment, which offer a historical and more formal twist to the classic phrase. Ultimately, the choice of synonym will depend on the context and tone of the writing, but all of these options serve to emphasize the act of writing by hand.
