3 Subject Notebook Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Five Star is the best-performing 3 subject notebook brand in July 2026, moving 58,000 units across 4 ASINs for 43.9% of Top 10 volume. Mead follows with 38,000 units (28.8%), ahead of Oxford on 29,000 units (22.0%).

With 4 brands splitting the Top 10 and 94.7% 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 $4.87 to $7.88, 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, 2 ASINs forced its way in: B071XQ65N8 booked 8K units at $4.77, with ▲ 700.0% MoM change. On the growth side, B091V5NF5T leads positive momentum with ▲ 700.0% MoM growth on 400 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
