zebra pen mildliner double ended highlighter

Each Mildliner is double-ended: one broad chisel tip for highlighting and bold lines, and one fine/bullet tip for underlining, lettering, and detail work.

The ink is soft and translucent/mildly pigmented. It’s described as a water-resistant pigment that minimizes bleed-through on thin pages and can be layered once dry.

Reviewers often report good performance for highlighting and journaling with minimal bleed on thin paper, and they praise the muted/pastel color range. A few shades are noted as darker than some users expect.

Listings vary: the fine/bullet tip is typically around 0.4–0.5 mm, while chisel/broad tip sizes are reported inconsistently (some sources list 0.6 mm and others list a 5 mm chisel).

Product descriptions state the markers are AP certified non-toxic, and some listings simply list them as non-toxic.

They use translucent ink intended to minimize bleed-through; reviewers commonly report little to no bleeding on thin paper. There is an occasional note of smudging when used with certain pen inks.
