When I had my consultation with the vision impairment specialist, he suggested I invest in a Pentel pen. Usually he gives a freebie to all his clients but unfortunately he had run out. He said I was able to get the pen from my local Officeworks (stationary shop) and they came in a range of colours.
To my great disappointment, my local Officeworks didn't stock the particular pen, and I had to order them online in a box of 25 all black. So of course I procrastinated because 25 black pens was not appealing to me.
Today turned out to be my lucky day. My friend and I ventured to Officeworks to discover a huge new wall full of pens. Of course we had to try every one out and we found the Pentel I was looking for!
The Pentel's I bought are the S520 Sign Pen (0.8mm). They look like a marker but they write like a pen except in a more bold ink, making it easier to read. It also doesn't seep through the page unlike standard markers. The pens cost me $2.71 each (I bought 7!).
Definitely worth a try! I highly recommend.
