What if you could write-off cancer and put a smile on someone's face? It is Diane's Pen Pals' mission to carry on a tradition that was once started by a woman whose zest for life and people was reflected in the countless notes she sent to family and friends. Use this pen to continue her tradition as we donate* the funds to write-off cancer.
