FINE Markers 0.005mm Black

I buy UniPin Fineliners regularly, and they’re a favorite in our household. These pens deliver sharp, consistent lines that are perfect for sketching, drawing, or detailed writing. The ink is richly pigmented and doesn’t smudge, even on lighter paper.They’re long-lasting and reliable, making them ideal for both casual and professional use. Whether you're outlining a drawing or adding fine details to artwork, these fineliners handle the job with precision. I’ve never been disappointed with their performance, and they remain my go-to choice for quality pens.

Nice fine line pen, dried quickly and great value for money

Thought it would be extra, extra fine tip as described as 0.005, hence bought 2, it isn’t. It’s still a fine nib and I like the pens, used them before.

Really fine and really good.

I keep the cap on when I am not using. in total i wrote alphabets of less than on an A5 paper after 1 month. then it dry out totally

brilliant this is had my doubts at first whether calling it 0.05 mm the narrowest thinnest pen have ever encountered was just misadvertising or just an accepted fake measurement just overlooked by most purchasers but NO it was niggling me so had some doubts so got out my microscope set it on 75x min settings dont need too high a setting then placed it under a plastic transparent template with millimetre scale divided by tenths of a millimetre you know really small looking at with the naked eye but HUNDRED MICROMETREs (microns) each quite big when measuring microscopic bugs spores bacteria etc anyway after a few trial and error attempts you have to really be slow and careful moving the nib in and out or sideways so it just gets picked up by the viewing lens measured it at around 0.35 to 0.40 mm just under half a mm to around a third (or slightly more) of a millimetre which made me think "see" they were wildly exaggerrating BUT then drew a line across the template scale and then measured it and it comfortably fit between a tenth millimetre scale gap arriving at the conclusion that it the width of the drawn line was much narrower than the nib estimating it at around 0.06mm to .08 mm which is nearly the width advertised very pleased an elated at the measurement measured some more lines so theoretically if you drew a line quite fast on a smooth surface you could actually arounf 0.04 mm which is even less than the advertised thickness the faster and lightly pressured on the nib is the thinner the drawn line wow i thought brilliant relievedi thought id open up the pen using a wire cutter grip with the pen wrapped in some tissue paper pulled the tight top off opposite end of the nib and used a tweezer like forcep to pull out the well you can say cartridge more like a long cylinder of cloth soaked in black ink wrapped around by a clear plastic sheet the type used for felt pens and fibre tip pens so when you eventually run out of ink which shouldnt be for a while like the other chap who reviewed it said just use a dropper or a syring probably better and inject a third of the way inside the felt column depending on how much you used it the longer youve used it the deeper the inject and inject about half a millilitre or more of black ink probaly the aqueous kind not too watery not too thick to keep replenishing itthere is plenty of ink the chap said 50 detailed sketches for about eight months i have heard parker ballpoint pens have refils that last long with about five miles of ink so this has probably got around a mile or so so if a parker pen gives you around 300 to 400 A4 sheets of lined paper full of writing this pen should give you around 80 lined paper sheets A4 sized plenty to go on may even last more than a year before it dries up so keep that cap on the nib hope that helps insha Allaah

Nice pen but is not 0.05. Received 0.5

I love these pens. They're smooth, consistent, stay sharp edged on the page, don't tire your hand out from holding, and help me finalise a lot of detail work from illustration. The black is a good proper black, not dark brown as you'll find on other pens. The line quality is as good as the larger sizes (the same cannot be said for some much more expensive pens...Rotring I'm looking at you).The one thing to bear in mind is this. If you are doing draught work, or type work, where you categorically have to have 0.05, then this, or any other fibre tip pen is not for you. You need to put your hand in your pocket and buy isograph or rapidograph pens. As long as you know this, and are working with a similar type of nib, you'll get on fine as it delivers half the line width of a 0.1 pen.If your looking at a pen like this, you already know what your looking for. Crisp, black, line with consistent flow, that matches up size wise to pens of the same or similar brand.
