Rotring Tikky Graphic Technical Pen | Inktober Art Supply Review

Rotring’s Radiograph and Isograph are probably the most well-known technical pens and that they had been in the market for a very long time. But how does their cheaper, non-reusable version stand up?

Facts Where Does it Stand?
Name Rotring Tikky Graphic
Color Black
Tip Size .1, .2.,.3, .4, .5, .6, .7, .8
Tip Material Metallic fibre-tip
Reusable? No
Type of ink Pigmented
Archival? Uncertain
Made In China
Price $3.50

I didn’t have any problem using these pens. The alliance that I got from them were not quite as crisp as I would prefer, even on very thick Bristol paper. Because of that, I probably wouldn’t be using them very often for delicate work.

Quality Where Does it Stand?
Drying Speed .1 mm dries in two seconds, .3 mm dries in three seconds, .5 mm dries in eight seconds
Pooling The bigger sizes will pool if left in one spot
Feathering Feathers on Bristol paper
Bleeding/Showthrough none
Appearance over Pencil normal
Waterproof yes
Copic/ Alcohol Marker proof yes
Eraserproof yes

Pros and Cons

Pros Cons
Line is dark black and pretty solid Bleeds on Bristol paper
Ink flows very quickly and smoothly Makes a thicker line than some other pens for the same size of tip
Ink reservoir window lets you know when the pen is running out Ink can smudge even when you think that it is dry
Copic, water, and eraser proof Bigger sizes pool ink at the end of lines

Who is it for?

Anyone who really wants a technical pen that can keep up with their fast movements. Since the ink flows very quickly, there is no stopping or sputtering of the line. This is great for anyone who doesn’t want to slow down.

However, depending on the way you like to draw, the ink might actually be too much. It bleeds a bit, and the lines are a bit thicker than normal. If you want superduper fine delicate lines, this is probably not the pen.

Art Supply Review: Uni Posca Paint Brush Pen (PCF-350)

Calligraphers are always looking for the perfect white ink, but what about the perfect white brush pen?

I’ve only ever seen a few, and so I had to try out this Uni POSCA when I saw one.

It's an ink-based brush pen that uses a pump system to deliver the pigment. Pretty unique, huh?

Ability to Flex Stiff
Tip Size Medium

Acidity Acid Free
Toxicity Non-toxic
Color Availability 60 Colors


  • It’s a white brush pen!

  • You could use the Uni Posca for accents and really large brush lettering on toned or black paper, which is pretty cool.

  • Totally unintended, but you can mix the pigment from the Uni Posca with pigment from your water soluble pens (like the Winsor and Newton watercolor marker or the Tombow dual brush pen) to get pastel shades. That’s so cute!

  • You can use the Uni POSCA to write on unconventional surfaces. It will even write on glass, rocks, or porcelain. Basically, it will work on any surface you try! (Keep in mind that the paint can be wiped or scratched away on nonporous surfaces)


  • The white is not totally opaque, and the brush can get pretty dry unless you’re constantly pumping the button.

  • The bristles don’t really come to a sharp point, so it’s hard to get good detail with this brush. [1]

  • Did I mention how much I hate pumping the button? ‘Cause it’s a lot.

My Rating: ★★☆☆☆

I had so many expectations for this price, but I don’t think I’ll be using it very often. I just hate that button, and no matter how many times I press it, I just can’t get the ink to be as juicy and wet as I want it to be.

Bristle brushes are generally harder to control than felt brushes, so I don’t think I would recommend this to a beginner.

In the end, it’s probably easier to work with an actual brush than the Uni POSCA brush pen.

  1. It is also possible that there is a fine point version of this pan, which would make me very excited!  ↩
