We were very successful using these! The hardest part was getting my newborn to unclench their fist (lol). We found each ink pad got 2 stamps out of it. And there were tons of papers and they were thick so nothing bled through. We got perfectly quality prints with no smudges. Truly it’s about how cooperative your subject is, we did a couple test runs but again, plenty of extra papers and pads to do so. It’s exactly what I wanted!
