My small Archival Ink sepia pad finally dried up, and I ordered this jumbo-size pad. The advantage to its size is that I can ink up a whole stamp at once, instead of tapping various portions of the stamp to the smaller pad.
The Archival Inks dry waterproof, so I can use them in conjunction with watercolors. I like the sepia color better than black for baby stamps and flowers, or any stamp where I'm going to be painting the inked image with pastel colors. Sepia and black are the two ink colors that I can't do without.
