The diary has pre-printed pages with the days of the week in two different layouts and allows you to add the year, month and date. Throughout there are small doodles and pictures but they don't take up the valuable space you use to write in. The only reason I've not given this five stars is because when you change between layouts, you either miss or gain a Sunday. For example, layout one is from Sunday to Saturday and layout two is from Monday to Sunday so you either get a Saturday followed by Monday or Sunday followed by Sunday. I've been using Fine Line Drawing Pens in the diary (also purchased through Amazon) and they show a little through the paper Taotree Fineliner Pens Coloured Set Fine Point 0.38mm in 10 Assorted Colours No Duplicates for Bullet Journal Artists Fine-Ink Drawings and Adult Colouring Books (Pack of 10 Fineliner Pens)
The book itself is in a slip cover which has a small pocket front and back and also a loop for holding a pen. I've not tried this for durability but it looks to be reasonably robust. The last few pages of the book are lined, plain and squared for your own notes. There are also the odd list page and divider page spaced out through the book.
I mainly got this as I was looking for a diary I could personalise and play around with before moving onto a bullet journal and it is certainly allowing me to try out different ideas and ways of recording information.
