Red Pen Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

BIC is the best-performing red pen brand in July 2026, moving 37,000 units across 5 ASINs for 52.1% of Top 10 volume. PILOT follows with 20,000 units (28.2%), ahead of Paper Mate on 10,000 units (14.1%).

With 4 brands splitting the Top 10 and 94.4% 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 $5.28 to $8.11, 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. Specifically, one ASIN forced its way in: B00006IE7A booked 3K units at $3.89, with ▲ 50.0% MoM change. On the growth side, B0CYRFJX34 leads positive momentum with ▲ 900.0% MoM growth on 1K units, with B001GXHEYK close behind at ▲ 500.0% MoM on 600 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
