I can answer this!
This agenda pages are undated, the quality of the paper is beautiful. If you write hard like me, you have some minor bleed through. Each month is a different color. I used pencil last year for this book, then erased it to use the pages a second time. I would never do that again, nor recommend that, it was painfully time consuming. This year I’m using mine as a thought journal. I have a blank one for next year. In all honestly, I’m not sure this was the smartest use of funds. I did buy it initially as a planner, but I didn’t find it that user friendly because there are only 2 days per page. Hard to get a sense of your week that way. I have the small size and it’s a nice enough size. A little big to tote around daily if you have a smaller bag.
I had also purchased the watercolor paper which was amazing, but I sent it back because 60 dollars for a small book of watercolor paper doesn’t make sense, especially when the cover is leather and leather isn’t happy around water. But the paper was lovely.
