Mr. Hobby GSI Creos Gundam Marker Pour Type Panel Lining Pen Trio Set (GM301 Black, GM302 Gray, GM303 Brown) for Gunpla & Scale Model Kits

Hands-Free Capillary Flow for Lightning-Fast Panel Lining:

Drastically cut down your panel lining time with the Mr. Hobby GSI Creos Gundam Marker Pour Type (Nagashikomi) Trio Set (GM301, GM302, GM303)! Unlike traditional fine-tip pens that require you to draw out every millimeter of a panel line by hand, these "Pour Type" markers harness capillary action: simply press the spring-loaded nib lightly into a recessed groove, and the ultra-low-viscosity fluid automatically rushes along the channel to fill the seam in seconds.

Complete Three-Color Shadow Spectrum:

• GM301 (Pour Type Black): The definitive choice for dark plastic components (navy, charcoal, dark grey), mechanical vents, thruster housings, and high-contrast comic lining.

• GM302 (Pour Type Gray): Formulated for white, off-white, and light grey outer armor plates, producing clean, subtle scale shadows without harsh contrast.

• GM303 (Pour Type Brown): Formulated specifically for red, yellow, orange, and gold armor pieces to yield natural warm-tone panel depth.

Spring-Loaded Pump Action & Effortless Erasability:

Each marker features an internal valve and spring-loaded felt nib. Depressing the nib charges the reservoir, allowing the oil-based fluid to flow freely into mold recesses. Any excess ink or pooling at the touch point can be cleaned away after drying for 1–2 minutes using a soft pencil eraser, a cotton swab dipped in rubbing alcohol, or the Gundam Marker Eraser (GM300).

(Note: Recommended strictly for unpainted polystyrene [PS] plastic parts. Avoid applying directly onto ABS plastic or painted surfaces, as the solvent can weaken ABS joints or dissolve acrylic undercoats.)

Key Product Features:

• Authentic GSI Creos Japan Quality: Official Bandai-endorsed detailing tools engineered specifically for plastic model builders.
