Our stamps are made from yellowing resistant photopolymers. These polymers are designed and produced for the printing industry and are meant to carry and transfer ink, which is why they stamp so well.
Photopolymer clear stamps can and should last a life time. There is no specific life span on photopolymer clear stamps, with proper use and general cleaning and care they should last as long as traditional rubber stamps.
It is recommended to store your clear stamps out of the sunlight and/or heat.
