The rubber stamp industry has retail sales of approximately $500 million annually. As the industry continues to adjust and modernize, more electronic products (i.e. electronic stamps, e-signatures, etc.) will become available, and these new items along with existing products should increase sales in upcoming years.
Daters, message stamps, address stamps, teacher stamps, notary stamps, and signature stamps are all popular items. Also, traditional stamps and stamp ink pads have experienced a resurgence of popularity with scrap-bookers and arts-and-crafts people.
