The pages inside are a lovely yellow colour with white ruled lines. The yellow looks like this (I modified the colouring slightly to try and reflect the true colour of the paper inside):
The thought of having a shelf full of (filled!) colourful notebooks has me salivating. I also found an orange Pantone notebook with orange paper inside (orange is one of my favourite colours!) but it was a bit too battered to justify it's price tag unfortunately.
I have yet to try out the paper in this Pantone notebook as my intended use for it is when I go out to GP or hospital visits in the first year of my course, and if there is space, for use in my second year when clinical rotations start. Scary to think that clinicals start in a year and a half's time! It is the perfect size for this too. I don't have many notebooks in this size either so I might need to hope that TK Maxx receive another shipment of these so I can get a few for much less than the RRP.
Once my student loan comes in, I think it is quite obvious what my first purchase might be ;)
