This is felt tipped or other porous-tipped pens and markers.
In response to customers who want to use Gundam Markers for finishing coat, we are releasing new Gundam Markers for clear coat. Two types are available, glossy and matte (this product), so you can choose the one that best suits your expression. Also, since they are completely water-based and contain no solvents, they can be applied over Gundam Markers without damaging the base material. We recommend painting with the Gundam Marker Airbrush, but painting with a pen is also possible.
