I've been specifying art supplies for a design studio for nine years. I've personally made (and documented) enough marker mistakes to fill a small binder: wrong nibs, wrong paper, wrong surfaces, wrong advice to a client. This is the FAQ I wish I'd had before my first big Copic order.
What type of markers are Copic?
Copic makes alcohol-based markers. The ink is dye suspended in alcohol, which is why the colors blend so smoothly and dry relatively fast. Copic is not a marker type like 'permanent marker' or 'highlight marker.' It is a brand name that makes several series: Classic, Sketch, Ciao, and Wide. The Sketch line is the one most illustrators know because it has 358 colors, replaceable nibs, and a refillable body. The Ciao line uses the same ink but costs less and has fewer colors. The Classic line is the older round barrel. Wide markers are for large areas. If someone asks me what type of markers to buy for a journal entry or a commission, I tell them to figure out surface and paper first, then choose a series.
One detail that surprises people: Copic color numbers are their own system, not CMYK and not Pantone. That means if you're trying to match a client's brand color, you need to test on the actual paper and check under the lighting you'll use.
Copic Sketch Markers in real use: a practical review
I search 'copic sketch markers reviews' more than I should admit. I think most reviews focus on how smoothly they blend—and they do blend beautifully. But the value case is less obvious. In my last restock, a Sketch marker cost about $8. A replacement nib was about $2–3. A bottle of refill ink was around $7 and fills a marker many times. I have Sketch markers from 2018 that are still going because I refill them instead of throwing them in a drawer. Our studio cost-per-project has gone down since we switched to refillable markers.
That said, I'm not going to tell you cheap markers are evil. If you're testing whether alcohol markers are for you, buy a small set of a cheaper brand and see if the hobby sticks. When you decide to commit, buy Copic refillables. The total cost over three years is usually lower than replacing disposables every few months. That's not a claim that Copic is the cheapest—because it's not—but it can be cheaper per use over time.
Can you use Copic markers for a journal entry?
Yes, but paper is the whole game. Alcohol ink is runny, so it soaks through ordinary paper. A standard US copy paper is about 75 gsm. For Copic work, I look for at least 160 gsm, and even then I test. I remember ruining a new journal in 2019 because the pages looked thick and the ink didn't bleed immediately. Ten minutes later, every drawn shape ghosted through to the next page. If you're doing a journal entry with Copic markers, put a spare sheet behind your page, test a corner, and don't trust the 'thick paper' label on the journal.
For serious blending in a journal, use marker paper or a mixed-media journal made for wet media. You'll still get some bleed-through on the back of the page, but the next page will stay clean.
Can you use Copic markers on a dry erase board?
I need to tell you a short story. In 2022, someone in our studio labeled a dry erase board with a Copic Sketch marker because it was close enough to a whiteboard marker. It looked great. Then we couldn't erase it. Copic ink is alcohol-based, so it can write on non-porous surfaces, but it is not a dry-erase formula. Once the alcohol dries, the dye sticks. Rubbing alcohol took off most of it, but 'URGENT' left a ghost that stayed on that board until it was replaced.
So, can you use Copic markers on a dry erase board? Physically yes. Should you? Only if you intend to make that drawing permanent. If you need a temporary label on a board, use an actual dry erase marker.
Can you use acrylic paint on glass?
This question usually comes up because people want to decorate a glass jar or water bottle with marker-style artwork. Acrylic paint on glass can absolutely work, but it needs preparation. The glass should be clean and dry. Many acrylic paints need a primer or a medium formulated for glass, and most need time to cure before the piece is handled or washed. I'm not a coatings chemist, so I can't tell you exactly which formula works for every paint bottle. What I can tell you from a studio perspective is that Copic markers are not the same thing. Copic ink on bare glass will smear, smudge, and lift, even after it dries. If you want marker-style art on glass, use paint pens or enamel markers made for that surface.
How should you store Copic markers so they don't dry out?
Here's the thing vendors don't always say: Copic markers can dry out even if you barely use them. The cap needs to snap shut completely, and the marker should be stored horizontally. If you store them nib-down, the ink pools in the cap and can make the nib dry faster. Keep them away from heat and direct sunlight. If a marker does dry, don't throw it away. Add a few drops of the correct refill ink to the barrel, let it sit for an hour, and test. I've brought a two-year-old 'dead' marker back to life this way. The cost of one refill bottle is less than the cost of replacing multiple markers, which is the real reason Copic's price tag makes sense if you maintain them.
