Collection stamps are a fast and effective way to send payment reminders to your customers. This ExcelMark A-1848 custom stamp features a 11/16" by 1-7/8" rectangle impression area and a durable, yet lightweight, plastic construction for long-lasting use. A self-inking mount re-inks the dye before each impression, making it ideal for quick, repetitive stamping. In addition, a unique, reversible (two-sided) ink pad doubles the life of the pad. Simply push it out, flip it over, reinsert and keep stamping! Each side of your ExcelMark ink pad initially lasts for thousands of impressions and is simple to re-ink and replace. A clear base on the mount allows you to easily line up those impressions.
