UNI Pin 5 Piece Black 01 - 08, UUAPIN5B

These pens didn't last very long at all before they started showing inconsistent lines, making drawing with them frustrating. I certainly wouldn't use them for any drawing I'm precious about.

Brilliant set of pens to use to highlight parts of painting

Great price for pens that do the job well. Nice for something to exceed expectations.

These lasted for almost two years and I used them almost every other day. In fact half of them still work but the thinner ones dried out at the end of last year. I draw neotraditional and comic style art and I use thick outlines on my work, and this brand of ink is incredible! It dries almost immediately so it doesn't smudge and my alcohol based pens doesn't merge with the ink. I tried watercolour on top of it and the black didn't hold up as well but honestly I semi expected it- I then drew on top of the colour but it ruined one of my pens by drying it up.They're comfortable to hold, the pen tips don't break or bend with pressure, the ink is pitch black and struggles to run, and they lasted me a long time. The ONLY thing I don't like is how the metal on the lid started to smell weird after a while. It doesn't affect the product or anything but I hate touching metal as it is, so any that smells make me uncomfortable. Other than that these are perfect and I already own a second pack!

A nice selection of tip sizes. I've used the pens on a number of projects and the tips have remained consistent and the colour has stayed as intense as it was when I bought them.

Didn't last more that two outline pictures, not very good as the are great to start, try filling the pens all the way before you sell them.

These are intended as a Christmas gift for my Daughter who is at Art college. She has used these before, for her favourite side line, which is drawing and digitising Bird illustrations. She produces wonderful pictures that are then printed on all kinds of merchandise via her purveyors site.This pack contains a good range of nib thicknesses and the pens last a reasonable length of time. Certainly, a good cheaper option to things like refillable Rotring Isograph drawing pens which tend to dry up and clog during storage in my experience and especially in the narrower sizes.They are good enough that we come back for more when she needs them and at £1.26 per pen they are cheap enough. The only down side is the plastic packaging and single use plastic pen bodies.

Better than I expected. Ink nice and deep black colour. and the ink doesn’t bleed with application of watercolour over the top of the ink drawing. The largest size pen in the pack ie 1.0 was a little scratchy on heavy weight mixed media Daler Rowney paper surface to start with and it,s probably not ideally suited for that; but with careful use soon began producing a nice smooth line.I,ve used Rotring isograph pens extensively, and these uni fine liner pens are every bit as professional although different and are definitely more versatile in my opinion. One pen lasted for one A2 size drawing. It becomes obvious as you are drawing when they are beginning to run outGreat product.Highly recommended
