Are acrylic markers oil-based or water-based?

Acrylic markers are both oil-based and water-based.

Oil-based acrylic markers use oil-based acrylic paint, which contains oil components and evaporates quickly. The color is based on the color after drying. In addition, the color saturation of oil-based acrylic markers is low, and the color after painting is different from the actual color, and it is difficult to modify on paper. Water-based acrylic markers use water-based acrylic ink, which does not contain oil, has a mild taste, and is not volatile. The color saturation of water-based acrylic markers is higher, the ink can be dissolved in water, and the painting effect is more transparent and natural.

Marker pen (English: Markerpen), also known as marker pen, is a drawing colored pen specially used for writing or painting. It contains ink itself and usually has a pen cap attached. It usually has a hard tip. The paint of the marker pen is volatile and is used for one-time quick drawing. It is often used in designing items, advertising slogans, poster drawing or other artistic creations.
