Most of the blog discussion concerning Lamy Safari pens seem to be around their fountain pens. Everybody seems to like them and for good reason. As you can see I have three of them. I have used them all at least once but with so many pens wanting to be in the daily rotation it is hard to use the same fountain pen everyday. That is why I like the rollers. Easy to use and all of the ones I have work fine. I do like the limited edition colors but I was not able to find a Aquamarine roller ball so I got the ball point. I would guess that over the years some limited edition colors did not have a roller. Looking forward to the next limited edition Lamy. The 0.5mm pencil writes just fine. As I have said before, I like color and I like clear. Lamy gives me both. Add them all to your collection.
