Paint marker Sakura XPMKAUV336 — blue ink, 1 pc, marker for permanent marking

Sakura XPMKAUV336 is a single-piece paint marker with blue UV-reactive ink designed for durable marking on a wide range of materials. The marker produces a fine 1.0 mm line and delivers blue pigment that remains discreet in normal light yet becomes vivid under blacklight. The body is one-piece and supplied as a single unit; colour-coded variants include black, blue and white housings. This tool is formulated for industrial labelling, craft accents, workshop use and general-purpose permanent marking where a chemically stable, waterproof paint ink is required.

Advantages

The Sakura paint marker combines a fine 1.0 mm nib with UV-reactive blue paint that is chemically stable and waterproof on many surfaces. Its paint formulation flows from an internal chamber to the tip after activation, providing consistent coverage on substrates such as paper, cardboard, plastic, metal, glass, wood and glazed ceramics. The invisible-in-daylight / visible-under-blacklight property enables discreet identification and special-effect applications without altering the visible appearance under normal lighting.

Suitable for

• Industrial and workshop labelling of tools, parts and equipment
• Craft projects, mixed-media art and hidden details in artworks
• Marking on glass, metal, plastic, wood, paper and ceramics
• Creating UV-reactive tags, secret messages and security marks

• Ink type: solvent-based paint ink, chemically stable
• Finish: opaque when applied; shows under UV illumination
• Suitable surfaces: paper, cardboard, plastic, metal, glass, wood, porcelain
• Format: single-piece paint marker supplied as one unit

How to use

Before first use, shake the marker vigorously with the cap on to mix the ink. To activate the flow, depress the tip several times in an upright position until the paint reaches the nib. Apply with steady pressure to produce an even 1.0 mm line; multiple passes increase opacity. Allow the mark to dry; drying speed depends on substrate porosity and environmental conditions. Note that adhesion and permanence depend on the surface and exposure to washing, abrasion, chemicals or extreme temperatures.

Usage recommendations

For best results, test the marker on a small inconspicuous area of the target surface to confirm adhesion and visibility under blacklight. Use on clean, dry surfaces and allow adequate drying time. Store capped, horizontally, and keep away from direct heat or freezing conditions to maintain ink consistency.
