I recently bought the Sea colors 6-pack of the Copic CIAO markers. The set comes with four, watery colors plus black and a clear blender. Each marker uses an alcohol based permanent ink and features a brush tip on one end and a chisel tip on the other.
In general, I think the Copic line of markers is popular with illustrators, particularly those in the comic book and/or animation business. When I was at the local comic book convention last month, I saw a lot of the artists had Copic markers in their kits. The CIAO is a smaller, less expensive version of the professional Copic Markers.
I absolutely love the springy quality of the brush tip. Its great for lettering. I’m a doofus with the wide chisel tip though. I blame my left-handedness.
Overall, the colors in the set were pretty though I never figured out quite how to use the blender pen. Because of the lightness of the colors, there was a little washiness in the colors that was not intentional.
After playing around with the Sai Watercolor markers, I was even less interested in the Copic CIAO markers but I suspect that these markers are not really made for the casual user. They reminded me a lot of the old DESIGN markers we were supposed to use in art school for “marker renderings” back in the day when digital photography and mock-ups were too expensive so artists would do a realistic drawing to show potential clients.
When dry, these inks were virtually waterproof which means that other water-based media, colored pencils or paint could be added to a drawing or calligraphy piece. On the right edge, I liberally applied water from a paint brush onto the markers after they were dry for a minute or so and the colors didn’t budge.
Then there was the bleed through issue. If you need markers like these for illustration purposes or for the waterproofiness, then the bleed through may not be an issue. For me, they bleed so much as to not be suitable for sketchbooks or even envelopes.
I will definitely use the black for calligraphy with the brush tip and the chisel end for labeling boxes (like a Sharpie Marker), but the other colors might not get a ton of use for my purposes. If I stumble across an illustrator or a young would-be illustrator, I will gift them the set.
Bottom-line: These are not for the casual user but more valuable to the artist, illustrator, animator or art student using heavy duty illustration board, specialty “marker paper” or the like.
