Ink Pens Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Sharpie is the best-performing ink pens brand in July 2026, moving 230,000 units across 5 ASINs for 63.9% of Top 10 volume. Paper Mate follows with 50,000 units (13.9%), ahead of PILOT on 30,000 units (8.3%).

With 5 brands splitting the Top 10 and 86.1% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $9.06 to $12.59, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. On the growth side, B01N6ZP7F5 leads positive momentum with ▲ 233.3% MoM growth on 10K units, with B082PMRSBK close behind at ▲ 200.0% MoM on 30K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
