The specific writing instrument favored by the former U.S. President is typically a Sharpie marker, often the black, ultra-fine point variety. This preference has been consistently observed during official document signings and public appearances where an autograph is requested. The choice contrasts with the traditional use of fountain pens or ballpoint pens commonly associated with formal occasions.
The use of this particular writing tool gained prominence due to its bold and easily legible ink, beneficial for signatures and documents intended for immediate distribution or display. The marker’s quick-drying ink also reduces the risk of smudging, crucial when dealing with numerous documents or interacting with the public. Furthermore, the Sharpie’s widespread availability and relatively low cost render it a practical choice for frequent use.
