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

PILOT is the best-performing rubic erasable pens brand in July 2026, moving 47,000 units across 6 ASINs for 68.1% of Top 10 volume. Grabie follows with 22,000 units (31.9%).

With 2 brands splitting the Top 10 and 100.0% 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 $12.12 to $14.03, 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: B0GGH8PJWL booked 4K units at $9.99, with ▲ 100.0% MoM change. On the growth side, B0FQMRNW4P leads positive momentum with ▲ 500.0% MoM growth on 300 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
