Abstract
A hand stamp includes a unitary marking structure having a plurality of ink-storing regions. The unitary marking structure has front and rear surfaces and substantially porous portions between the front and rear surfaces. The unitary marking structure has a first region adapted to store a first ink and a second region adapted to store a second ink. The first and second inks may be different, such as different colors. A substantially non-porous barrier is provided between the first and second regions of the marking structure to prevent the inks from migrating between the first and second regions.
