Posca PC-1M Extra-Fine Paint Pen - Black & White

The Posca PC-1M Extra-Fine Paint Pen is the precision instrument of the surfboard shaping bay. Proudly Made in Japan, these water-based markers feature an ultra-fine 1mm tapered tip, making them the industry standard for signing finished shapes, detailing complex logos, and drawing surgical-grade pin-stripes.

The PC-1M is designed for total control. Its small-diameter tip allows for effortless writing on shaped foam and is the preferred choice for shapers to ink their signatures and board dimensions on the stringer. It is equally effective when used on a sanded hot coat for adding intricate art or technical accents. The water-based pigment is highly opaque and lightfast, ensuring your fine lines remain sharp and vibrant under the glass.

Because the formula is solvent-free and resin-compatible, these pens are safe for use with both polyester and epoxy surfboard construction. For designs applied over a sand finish, we recommend a thin coat of clear acrylic spray to preserve the fine detail and prevent smudging.

Available Options:

• Black: The classic choice for shaper signatures, stringer notes, and bold outlines.
• White: High-visibility contrast for signing dark resin-tinted boards or adding highlights.

Key Features:

• 1mm Extra-Fine Tip: Tapered nib designed for writing, technical drawing, and ultra-fine detailing.
• Shaper’s Essential: The go-to pen for signing foam blanks and marking dimensions.
• Resin Compatible: Water-based pigment that won't "bleed" when glassed over with poly or epoxy.
• Made in Japan: Precision valve-action system for a consistent, skip-free ink flow.
• Opaque & Lightfast: Provides excellent coverage even on dark or vibrant surfaces.

Pro Tip: When signing a foam blank, keep a very light touch. The extra-fine tip is sharp enough to "catch" in the foam cells if pressed too hard. A smooth, gliding motion will produce the cleanest, most legible signature.
