The ExcelMark Do It Yourself stamp kit is the ideal choice -- enjoy a custom message that fits your needs every time you need a stamp! 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! This kit includes hundreds of characters for custom messages, tweezers to handle the characters, and a black ink pad. The impression area size of 7/8" x 2-5/16" is larger size than other leading brands. Use your DIY stamp kit for return addresses, business contact information, office needs and more! This item comes with a limited 1 year warranty against defect and workmanship.
