The Loop Water Based Brush Fineliner is a precision outlining tool that combines the control of a marker with the fluid expressiveness of a brush. It employs a flexible brush tip and a water-based, highly pigmented black ink derived from the classic LP-104 formula. This design allows artists to vary stroke width with pressure, creating everything from fine outlines to broader accent lines while maintaining rich opacity. The ink dries relatively quickly, is low odour, and works well on most smooth, non-porous surfaces.

Features and Benefits

• Brush Tip Design: Enables dynamic, variable strokes—from fine lines to bold strokes—based on pressure and movement.
• Water-based Black Ink: Offers dense, opaque coverage and strong contrast for outlining and sketch work.
• Smooth Flow & Control: The brush tip provides elegant transitions, ideal for expressive line work and detailed art.
• Compatible Pairing: Matches well with Loop’s water-based marker and spray systems for seamless layering.
• Low Odour & Safer Use: Being water-based, the ink produces minimal smell and is safer for indoor or studio use.
• Clean & Maintainable Tip: Easier to flush and preserve compared to rigid nibs, extending functional life.

How to Use

Shake the pen gently to ensure ink is evenly distributed. Start your strokes on scrap paper to “warm up” the brush and check responsiveness. Use light pressure for thin lines or increase pressure to widen strokes, adapting to your style and movement. The ink dries with minimal smudging, but it can be sealed if applied over slick surfaces. After use, flush the tip with a little water on a scrap area to clear residue and maintain smooth flow.
