My must have is coloured pens! I love writing in colour and it keeps me happy and interested in whatever I am doing. I am also very picky about the size of my pen tip and the thickness of the pen (OCD? yes, I know). Here are some of my faves...

These are my marking pens, my day book pens (yes, I write in ink! gasp), my note to self pens, everything I write is usually done with these pens! They are all over my classroom and my house.

Staedtler is also a good option although I find they don't stand up to the amount of writing I need to do during a day and dry out quickly. Still fun colours though.
Lastly, if I am going to write in blue then it better be these pens...

They are getting harder and harder to find in stores here in Canada so it looks like online shopping for me!
