I have used this brand before, about 15 years ago. It hasn't changed as a product or in quality. From this specific one, I used 01, 05, 08, and PN where I had no problem, it did the job for me and it was as if nothing had changed from the old days. I should mention that I used to use it as a rapidograph with very good response.

Unbelievable quality that is worth every euro! The construction of the markers is very convenient and their tips are excellent for drawing architectural lines, as well as more free sketches. It also includes an everyday use marker in the package. The truth is that I wasn't impressed, nevertheless I definitely recommend it not only for architects but also for artists who are into sketching.

I have been using this specific brand for about three years and it is one of the best markers I have tried. The tip is very difficult to break and the ink is waterproof and vibrant. My favorite thickness is 0.02, but I believe it depends on what each person wants to draw :)

Amazing quality. They don't smudge and can be used in combination with various materials (watercolors, markers)
