Rotring 600 Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Pentel is the best-performing rotring 600 brand in July 2026, moving 12,000 units across 3 ASINs for 37.5% of Top 10 volume. Uni-Ball follows with 8,000 units (25.0%), ahead of Nicpro on 4,000 units (12.5%).

With 6 brands splitting the Top 10 and 75.0% 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 $7.66 to $12.48, 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: B0047CT6SE booked 4K units at $4.53, with ▲ 300.0% MoM change. On the growth side, B0D9MLK72Z leads positive momentum with ▲ 350.0% MoM growth on 900 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
