The Ohuhu Fineliner set is eight black micro drawing pens in eight tip sizes: 0.2, 0.25, 0.3, 0.35, 0.45, 0.5 and 1 mm, plus a brush tip. Each pen has its tip code on both the cap and the barrel to prevent mixing them up.
The ink is an archival, waterproof pigment ink that Ohuhu describes as fade-resistant, acid-free, quick-drying and bleed-proof. It works with alcohol markers, water-based markers and pencils, as long as the ink is fully dry before alcohol markers go on top.
Based on the manufacturer's Amazon listing.
0.2 mm (0.05), 0.25 mm (0.1), 0.3 mm (0.2), 0.35 mm (0.3), 0.45 mm (0.5), 0.5 mm (0.7), 1 mm (1.0) and a brush (B), from ultra-fine detail to thicker strokes.
Archival quality ink that Ohuhu lists as waterproof, fade-resistant, acid-free, quick-drying and bleed-proof.
Use the fineliners first and let the ink dry fully before layering alcohol markers, which can smear wet ink.
Each pen shows its tip code on the cap and the barrel, so you can pick the right size directly.
The round barrel gives a comfortable grip and the caps stop the pens rolling off the desk.
Ohuhu describes the pens as non-toxic and odorless.
Look elsewhere if: you want colored line work as well as black. The Ohuhu Colored Fineliners (18) add 11 colors to 7 black pens.
