I know you probably won't care, but I bought this pen for my husband on our son's anniversary of cancer treatment. He was having a tough time of it, and so I bought him your pen — he loves copper — based on a recommendation from a Dad's oncology group. They told him to get him writing and vent his frustrations on paper, and what better way to do it than with a nice pen.
I just wanted to say thank you for calming my man and giving him some ability to let his anger go on paper. It has been a real help.
Our son is doing well, but it is still a journey. Thank you for the help he needed.
This email is why we do what we do. "Write Your Story With Us®" — at its core, this is exactly what that means. We are so honored that our pen found its way into your family's hands during one of life's hardest chapters, and we are beyond grateful you shared it with us. We are cheering your family on every step of the way.
