Field Notes Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Mead is the best-performing field notes brand in July 2026, moving 10,000 units across 1 ASIN for 31.3% of Top 10 volume. BIC follows with 10,000 units (31.3%), ahead of NIRMIRO on 3,000 units (9.4%).

With 9 brands splitting the Top 10 and 71.9% 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 $7.33 to $13.87, 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: B08N5YPN3Q booked 1K units at $8.99, with ▲ 233.3% MoM change. On the growth side, B07DGBJXC4 leads positive momentum with ▲ 200.0% MoM growth on 300 units, with B01MQFDNSH close behind at ▲ 100.0% MoM on 200 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
