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

ARTISTRO is the best-performing posca markers brand in July 2026, moving 60,000 units across 2 ASINs for 74.1% of Top 10 volume. Pagather follows with 8,000 units (9.9%), ahead of posca on 7,000 units (8.6%).

With 5 brands splitting the Top 10 and 92.6% 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 $9.97 to $33.07, 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: B013NMZ6XC booked 1K units at $33.43, with ▲ 233.3% 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
