Gundam Panel Line Marker Pen No-Wipe Flow-In Formula Set of 3

Crisp Panel Lines. No Wiping. No Mess.

Achieve sharp, professional-looking panel lines on your Gunpla builds without the hassle of enamel washes or endless clean-up. These flow-in panel line markers use a low-viscosity ink that wicks automatically into recessed lines by capillary action — just touch the tip to a panel line and watch it flow. The no-wipe formula means the ink stays exactly where it belongs, leaving surrounding surfaces clean and ready for topcoat.

Key Features

• No-Wipe Flow-In Formula: Ink flows into panel lines automatically and dries in place — no solvent wiping or cotton swab cleanup required
• Capillary Action Technology: Ultra-low viscosity ink travels along recessed lines by itself for fast, even coverage
• Weathering & Panel Wash Effect: Creates realistic shadow and depth on panel lines, simulating battle-worn and aged finishes
• Fine Tip: Precision applicator tip for controlled application on 1/144, 1/100, and 1/60 scale kits
• 3-Pen Set: Three pens included — ideal for covering different panel line colors across multiple kits simultaneously
• Compatible with Snap-Fit Builds: Works directly on bare plastic for builds; also suitable over primer or base coat

What Is Panel Lining?

Panel lining is the technique of darkening the recessed grooves (panel lines) on a model kit to add visual depth and realism. It's one of the most impactful finishing steps you can do — transforming a flat-looking snap-fit build into something that looks hand-painted and detailed. This flow-in pen makes the process accessible even for complete beginners.

Who Is This For?

Perfect for Gunpla builders at any level — from beginners doing their first build who want an instant detail upgrade, to experienced modelers looking for a fast, clean alternative to traditional enamel panel washes. The no-wipe formula is especially valuable when working on white or light-colored kits where solvent damage is a concern.

Frequently Asked Questions

Q: What does "no-wipe" mean — do I really not need to clean up after applying?

A: Correct. Unlike traditional enamel washes that require wiping excess ink off surrounding surfaces with a solvent-dampened swab, this flow-in formula is designed to stay within the recessed panel line. The ink dries in place without spreading onto flat surfaces, so no cleanup is needed in most cases. A light touch on application gives the cleanest result.

Q: How does the flow-in (capillary action) application work?

A: Simply touch the pen tip lightly to the start of a panel line. The low-viscosity ink will automatically travel along the groove by capillary action — the same principle that draws water into a narrow tube. You don't need to drag or press the pen; the ink finds its own path through connected lines.

Q: Can I use this directly on bare plastic without a primer or topcoat?

A: Yes. These pens are designed for use on bare plastic builds. For best results, ensure the surface is free of fingerprints and oils. If you plan to topcoat afterward, a matte or semi-gloss topcoat will seal the panel lines and protect the finish.

Q: Will the ink damage or crack the plastic?

A: The no-wipe formula is designed to be plastic-safe when used as directed. Unlike enamel thinners (which can cause stress cracking on ABS plastic), this pen's formula does not require solvent wiping, eliminating the main risk factor associated with traditional panel washes.

Q: What colors are included in the 3-pen set?

A: Please refer to the product images and variant options for the specific color combination included in this set. Common configurations include black, gray, and brown — covering the most widely used panel line colors for light, dark, and earth-tone kits.

Q: Can I use these pens on Master Grade (MG) or Perfect Grade (PG) kits with finer panel lines?

A: Yes. The fine brush tip and low-viscosity formula work well on the finer, shallower panel lines found on MG and RG kits. For very shallow lines, a light touch and allowing the capillary action to do the work will give the cleanest result.
