## Description

UNI PIN DRAWING PEN FINELINER ULTRA FINE LINE MARKER IN Black INK 0.3mm Tip Black INK Pack of 3

Review: ONLY 0.3mm - Thought I’d get one of each size pictured. I should have read the title more closely. —Writes well 👍 —cap makes popping sound 👍 —fair quality 👍 —Fairly comfortable —matte plastic feels nice —🎥 can fit a standard foam pencil grip around them (video) —on paper, doesn’t smudge 👍; water resistant —smudges on polypropylene plastic 😪 —seems to survive -80°C Flow: no issues (may be quick to dry if left uncapped) Bought because I need to write on appended tubules (made of plastic) and wanted to see if anything would be better than Sharpie. This is too easy to wipe off of plastic—but I only heard this through word of mouth and not the product description so I didn’t take off stars.
Review: Excellent pen for writing and sketching - If you like a using a pen that write a fine line smoothly, this is it. I use this pen for both writing and my sketching and watercolor paintings. The ink is dry, waterproof, and ready to paint in about 5 minutes. After five minutes the pen's lines do not smug when going over them with an eraser. I have used dozen of these and have never had one malfunction. I wish the gel lasted longer in the pen.
