Posca Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

ARTISTRO is the best-performing posca brand in July 2026, moving 65,000 units across 3 ASINs for 69.1% of Top 10 volume. Pagather follows with 8,000 units (8.5%), ahead of Grabie on 7,000 units (7.4%).

With 7 brands splitting the Top 10 and 85.1% 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 $15.31 to $22.08, 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: B0FMKQKK1D booked 5K units at $25.99, with ▲ 400.0% MoM change. On the growth side, B0BWYLS4BN leads positive momentum with ▲ 500.0% MoM growth on 600 units, with B001AS6P4G close behind at ▲ 400.0% MoM on 1K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
