This RETURN SERVICE REQUESTED stamp is a great tool for all those needing something quick and efficient on the go! When people move, they don’t always leave a forwarding address. So for packages and letters a stamp such as this may be necessary. Please keep in mind the standard size is .563" x 1.5"- if you would prefer something larger, we offer upgrades for as little as $2 extra. We also offer a variety of ink colors for you to choose from in the event you decide not go with black- changing to one of these other colors is free of charge.
