Wooden “Flat” Hand Stamp w/Knob Style Handle. These flat hand stamps are rib backed to be used with RIBtype® rubber type. Ribs on the back of the type interlock with ribs on the hand stamp. This allows for fast changes of text for date coding and lot number changes. Graphics can also be incorporated in the type for product and brand identification. For depth, figure 8ribs for the 1^st inch, then 7 ribs per inch thereafter.

It is probably best to call on these for determining the correct overall size needed for your application.
