Our stamps, including woodblock and clear, are made with quality and perfection in mind. For wood, we start with pure rubber that is molded with the deepest possible etch, and then cut and detailed by hand. Finally, the stamp is mounted on a sustainably harvested hardwood block we make in our own solar-powered facility. Our clear sets, too, are made with love and precision. We use only top-grade USA-made photopolymer resin, which is specifically formulated to hold ink and give a true impression. While many of our competitors have looked to overseas production, our photopolymer is latex-free, non-toxic, tear-resistant and deeply etched. No other stamps on the market exceed the quality and performance of Hero Arts stamps.
