Abstract: A hand stamp having an improved mechanism for accommodating an angular deviation between a stamp pad and a surface being stamped and a stamp and stamp rack set in which the stamp is easily engageable and disengageable with the stamp rack. A spring mechanism is provided between a stamp pad holder and a surrounding cover. The spring mechanism biases the stamp pad holder into a retracted position within the cover, and also helps to resiliently accommodate any alignment deviation between the stamp pad and the surface being stamped. The stamp rack is formed to easily receive and retain a stamp therein. Also, the stamp rack may include engagement structures whereby a plurality of stamp racks can be easily engaged to each other.
