Lets see. Im A4, which is always handy. Ive got a vibrant (and protective) cover plus 300 nice, thick (80gsm), easy to rip out pages, that are seven hole punched and margined too.
I bet you already found the penholder and subject name cut outs on my cover. And if you open me up, youll see two double-sided pocket dividers and a two-year calendar to help you get organised.
Just dont get too organised. Notebooks are for scribbling, sketching, experimenting and exploring. So go on. Be spontaneous.
