Mr. Hobby GSI Creos Gundam Marker Cleanup & Correction Duo Set (GM300 Classic Chisel Eraser & GM310 Twin-Tip Eraser Pen) for Gunpla & Scale Models

The Definitive Cleanup & Paint Correction Arsenal for Model Builders:

Tackle every detailing mistake, paint slip, and panel line overflow with the Mr. Hobby GSI Creos Gundam Marker Eraser Duo Set (GM300 & GM310)! Bringing together the high-flow classic chisel pen and the versatile dual-ended detailing pen, this duo gives you surgical control when cleaning up raw polystyrene (PS) plastic kits without stripping, clouding, or weakening the underlying parts.

Two Complementary Solvent Applicators:

• GM300 (Classic Chisel Eraser Pen): Engineered with a wide, spring-loaded chisel felt nib. Ideal for broad flat-panel cleanups and dispensing controlled solvent puddles onto work dishes to dip fine-point cotton swabs into.

• GM310 (New Twin-Tip Eraser Pen): Designed with a dual-ended configuration—a soft brush tip for sweeping across curved armor sections, and a fine angled tip for cleaning tight corners, mold crevices, and narrow recessed seams without washing out the lines.

Fast, Gentle, Plastic-Safe Solvent Action:

Both pens contain GSI Creos’ proprietary mild alcohol-based cleaner formulated specifically for the Gundam Marker ecosystem. They cleanly dissolve standard oil-based marker ink (GM01–GM03), capillary Pour-Type inks (GM301–GM303), and Gundam Marker paints on contact. Simply trace over the mistake, wait a moment for the solvent to lift the pigment, and wipe it away with a cotton bud or microfiber cloth for a flawless, factory-fresh finish.
