Inexpensive, and effective, but they are for me below Chartpak whose colors are more beautiful and really nice to use tip (tri-nib). Too bad there was not a top "brush". If not it's a great quality / price ratio, I recommended. I had two problems: - Had a felt tip that stood out, I stuck, no problem. - The canary arrived dry and unusable AC is not normal. I hope make me replace the yellow .... or of only 3 stars
