I have one of these, I purchased it shortly after my rape, the cause I choose was for the Boston Area Rape Crisis Center. They are well made, stainless steel. When I first got it, I never took it off. It was a reminder through some of the darkest times in the beginning of this tragic ordeal. Also, I believe that this site also allows you to create your own cause (but I could be wrong).
Additionally, there are SO MANY causes to choose from in mental health categories, heal categories….the list goes on!
