Our clear stamps are designed to be non-yellowing. However, this does not mean they will never yellow if not stored properly or taken care of properly. Also, they may stain from certain types of inks. So while they typically do not yellow, they may stain from inks and may yellow if not stored correctly. For optimum lifespan they should be stored in cool place and not in direct sunlight. Heat may damage the photopolymer material.
