Sets include very-fine fineliners (0.20 mm, 0.25 mm), several mid-fine points (0.35 mm, 0.45 mm, 0.50 mm), a 1 mm bullet tip, a brush tip, and a 0.7 mm fixed-sleeve mechanical pencil.
The pens use archival ink described as waterproof, chemical- and fade-resistant, quick-drying, pH-neutral, and formulated to be bleed-free on most papers.
Available multi-pen packs include examples such as 6‑pack and 3‑pack sets; specific pack sizes vary by listing.
They are described for manga and comic illustration, general drawing and doodling, writing in journals and planners, and for archival documentation and paper-craft projects like cards, letters, envelopes, and scrapbooking.
Reviews report smudge-resistant ink and reliable drawing behavior, praise the pens for producing consistent fine lines and precise results, and give generally positive impressions of product quality and value.
Listings describe the ink as smear-resistant or labeled 'No smears' and indicate it does not bleed through most papers.
The notes advise against using the pens on fabrics intended to be washed and state they have not been evaluated for cosmetic use on skin.
Some sets include a brush pen, a 1 mm bullet-tip pen, and a 0.7 mm fixed-sleeve mechanical pencil alongside the fineliners.
