Paint marker BRUYNZEEL SAKURA XPFKAUV336 — blue, 1 pc, paint ink

BRUYNZEEL SAKURA XPFKAUV336 is a single blue paint marker supplied as 1 piece. This Pen-Touch marker features UV-reactive blue paint ink that is nearly invisible in normal daylight but fluoresces under blacklight. With a medium 2.0 mm tip it produces consistent, opaque lines suitable for marking, labeling, decorative finishes and craft applications on a wide range of surfaces including cardstock, plastic, wood, glass, porcelain, paper and metal. The ink is chemically stable and designed for durable markings where a concealed or special-effect blue is required.

Advantages

The marker provides UV-visible blue paint ink that remains discreet in ambient light and lights up under blacklight to reveal vivid blue markings. Its 2.0 mm medium nib delivers uniform, opaque coverage for readable labels and decorative strokes. Pen-Touch ink is chemically stable and waterproof on many surfaces, offering resilience against moisture and everyday handling. The single-piece format simplifies purchase and storage for occasional or professional use.

How to use

Before use, shake the marker with the cap on to mix the ink and activate the UV pigment. Depress the tip in an upright position several times to release internal pressure and allow the paint to flow into the tip. Apply the marker to a clean, dry surface using moderate pressure to obtain an even, opaque line from the 2.0 mm nib. Allow the paint to dry; drying time will vary with surface porosity and ambient conditions. The visibility of the blue marking in daylight is minimal, but the ink will fluoresce under blacklight.

Usage recommendations

For best results, test the marker on a sample area of the target surface to check adhesion and drying. Use on non-porous surfaces may require longer drying time and can be more durable; on fabrics or surfaces exposed to frequent washing or abrasion, marks may fade. Keep the cap tightly closed when not in use and store horizontally to maintain consistent ink flow. Use under appropriate supervision for children’s activities and avoid contact with skin and eyes.
