purple liquid eyeliner

Several listings explicitly state suitability for the waterline/inner rim and call out ophthalmologist testing, hypoallergenic formulas, and waterproof/long-wear performance.

Product descriptions emphasize high color payoff, using phrases like “hyper‑pigmented kohl” and “high pigment density,” indicating strong pigmentation.

Many listings are described as long‑lasting; at least one product specifically claims color that “lasts up to 24 hours.”

The listings show multiple formats including liner/pencil, gel, and liquid eyeliner options.

Multiple descriptions list waterproof and long‑wear formulas; some specifically mention non‑flaking or fade‑proof wear.

Some products include built‑in or automatic self‑sharpening mechanisms, while others are marketed as not requiring sharpening.
