What are the criteria that Creative Memories pens must meet?
ISO 18902 standards. These tests ensure that journaling will not change significantly when exposed to direct sunlight for one year or when submerged in water for one day. Pens have a shelf-life of at least one year and will continue to perform even if accidentally left outside. The color remains consistent over time. In addition, all pens meet applicable safety standards, including ASTM D-4236, which requires art material to be tested and properly labeled for toxicity, and ISO 11540, which requires pens to be safe for children.
