Best Midliners Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
BIC is the best-performing midliners brand in July 2026, moving 80,000 units across 1 ASIN for 33.3% of Top 10 volume. Paper Mate follows with 80,000 units (33.3%), ahead of Sharpie on 40,000 units (16.7%).
With 6 brands splitting the Top 10 and 83.3% 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 $7.49 to $11.58, which frames the price band a competing listing has to justify.

Trending Midliners Products — Growth Leaders & New Top 10 Entrants
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: B0752WWCTN booked 10K units at $14.97, with ▲ 150.0% MoM change. On the growth side, B0CCJ6JKNQ leads positive momentum with ▲ 900.0% MoM growth on 3K units, with B0CQ6QY3WH close behind at ▲ 700.0% MoM on 80K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
