Liquid frisket typically requires brushes, which means constant cleaning and inevitable bristle marks in your masked areas. The Masquepen eliminates both problems with a precision applicator system that draws masking fluid like a pen. The 0.8mm nylon nib creates continuous lines, straight, curved, thick, or thin, plus individual dots for flower stamens, snowflakes, or botanical details without the mess of traditional application methods.

Pale blue water-based latex makes placement instantly visible against white paper, then peels off cleanly without damaging the surface once your washes dry. The formula works both under layers and on top of inks, watercolors, and acrylic washes, giving you flexibility in your masking sequence. A stainless steel prong built into the cap seals the nib between sessions so the fluid won't dry out mid-project.

The lightweight 1.25-ounce non-breakable bottle travels easily to plein air sessions or workshops. Refill bottles let you swap caps and continue working without interruption. An ultra-fine 0.5mm Supernib attachment creates spider-web-thin lines for the most delicate masking work. Sets bundle multiple nib sizes with refills for artists who mask frequently across different scales of work.
