Stay organized and ensure efficient communication with the use of this ExcelMark custom self-inking rubber stamp -- perfect for at home or the office! The self-inking design automatically re-inks itself into a rotating, self-contained ink pad before each impression, making it ideal for rapid, repetitive stamping. In addition, the two-sided ink pad gives you double the life. When the impression starts to fade, simply slide the pad out, flip it over, reinsert and keep stamping!
