1. Tip: The tip of a watercolor pen is generally round, while the tip of a marker pen is flat, which is divided into a fiber-type tip and a foam-type tip.
2. Ink: Markers are water-based, oil-based and alcohol-based, while watercolor pens have only one water-based type.
3. Coloring: Watercolor pens cannot stack colors, but markers can stack colors. Markers are easier to color than watercolor pens.
4. Use: The advantage of watercolor pen is that it has enough water, the color is rich and bright, and the disadvantage is that the water is uneven, the transition is unnatural, and the two colors are not easy to reconcile together, so it is generally suitable for children's paintings, and can also be used as a marker.
The advantage of the marker is that the water is uniform, and the disadvantage is that the color contrast is weaker, but the two can be well coordinated together, and can draw architectural renderings and industrial design renderings.
