## Description

Introducing a gundam marker pen! Simply knock the nib on paper and moisten the ink with the ink, then place the tip on the mold! It flows smoothly into the mold and allows you to insert thumbs. The protruding portion can be erased with an eraser or "GM300 Gundam Marker Eraser Pen" (sold separately). Note: Please do not overcoat other colors such as Mr. color. When used over the paint, the ink will melt the base paint. Applying a coating agent after painting may bleed. When used over plated parts, it will melt the plated surface.

## Questions & Answers

**Q: Can this be used on bare plastic or should i topcoat the plastic first?**
A: It depends on you really I don't top coat my kits and I use it on the plastic. I have seen nothing bad after using it on plastic.

**Q: Does it panlline 1/144 gundams**
A: Yeah it works on all scales and grades. I've found if you are having trouble getting a line to stick, gently tracing it with a needle helps the ink to flow and give a bolder look.

**Q: Does this pen with ink in it already or do I have to buy the ink bottle with it ?**
A: It has ink in it. You push the tip down on the surface to start the flow. The Gray version flows better than black, but they're both good to have, depending on the color of the piece.
