In terms of pure numbers, for me...this pen was probably the one that was bought and used the most this year. I would wager that I went through about 15 of these so far. Not because I lost them, or gave them away, but because I use them. Heavy. You can read my old reviews here and here if you haven't yet.
I am a list maker and I like the titles of my lists to be BOLD. That's where the sign pen comes in. I also have a heavy addiction to Post-its and these are perfect for making a quick note, sticking it up on the board and then knowing what I was supposed to remember.
The tips of these get better and better with every use. Out of the box they are long and sharp- but as you write with them, they just seem to wear perfectly. Never mushy, never dull. Creating a perfect point that stays there until the well runs dry.
I am not sure why this one is number 8. It seemed fair to put it there.. I use it a ton, but I don't really "write" with it or use it in my journals-- but it does get heavy use and I would have a hard time trying to replace it.
It's a good pen. The Christmas shopping is done, I did manage to buy 1 pen for a friend. That number is way down from last year. As a pen lover, it is really hard to give pens as gifts. You just never know what people will like, but I think I nailed it. I will give the details after the Holidays.
