As it was the first Guard Your ID product to be launched, the large stamp holds a special place in our hearts. Our journey to develop the stamp took some time. In fact, over 100 stamp patterns were tested, including x’s, circles, stars, checkerboards, and even numbers. After months of grueling research, it was finally determined that the best way to hide letters was, well, to use letters...and this took us one step closer to finalizing the patented pattern that we still use today. Our stamps continue to be a solid solution for protecting your information from identity thieves. They are easy to use, refillable, and will quickly stamp overprinted material to conceal your private information.
