I always find it fun to take a look at the top selling pens via Amazon, specifically the list of top selling rollerball pens, which by default should be some of the most popular rollerball pens based on the huge number of sales that Amazon generates. I usually find a gem or two in the listings, but I have to admit I was pretty disappointed with the batch of top sellers this time around. The majority of the top 20 in this list is made up mostly of the ubiquitously mediocre Pilot G2 and a bunch of generic looking sets of multi color gel ink pen sets. What happened to this list that used to be a decent barometer of some of the better pens out there? This may be a list of the most popular rollerball pens (ie most frequently purchased) but don’t mistake that quantity for quality.
