Our Clear Design clear sets 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 where materials may be substandard, our photopolymer is latex-free, non-toxic, tear-resistant and deeply etched. It always clings, is easy to clean and easy to store. No other clear stamp on the market exceeds the quality and performance of Hero Arts Clear Design.
