I have bought some of these as gifts for others as well as for my own personal use. I love that I never have to hunt down a pen to jot down a quick thought or add an item to a running list. I also categorize them for different uses by color. The red one is my health journal and the grey one is for on-the-go/ miscellaneous informational bits that can be transferred to my calendar/planner/phone during weekly planning times.
I am a big fan of the heart design because of the beautiful backstory. Brett designed this in honor of his dad and it is a symbol of their great love for each other. The visual of the hearts looped together reminds me at a glance to be sure to take time to show love to each person in your life as you are coming and going.
