Hi Kristina! Alcohol markers have ink and alcohol in them. They act more like paint, you can blend colors easier than water-based markers, and they don't streak as long as you work quickly. Ohuhu is my favorite brand. The downside is their price, and like anything else made with ink, they will fade over time. I have an affiliate link for 10% off on their website: loox.io/z/8EQv0EQBN
