I have purchased the bound 4 by 6 index cards as a journal to take to my medical providers. As a person who take a variety of supplements I am able to track my daily intake as well as if I miss. I find this product very useful and convenient.
Perfect to keep handy all the time. Put a clip pen in the spiral. Jot a reminder anytime. Also can share info with a friend immediately by tearing off the card after writing.
