Sat Feb 21 2026This is one is close to my heart since my fiancé gifted me this, when I first met him. I love the thoughtful quotes on each page and also the clear numbers on each page, makes it very convenient to use. The metal spiral is a very mindul add on since it can be laid flat anywhere and it stays like that, until you filp!
