Hi, my name is Maro Strifezza (AKA: Mariano Gonzalez). This compact personal stamp is easy to carry and square in shape for maximum portability. To activate it, simply cut a thin layer of sponge and insert it into the inner recess of the square holder, then soak it with ink so that the square impression always remains inked. The built-in dimensions ensure a secure fit without needing additional support or retention. Friction holds both pieces firmly in place, eliminating the risk of separation.
