Anti-Counterfeit Invisible UV MarkerTired of counterfeit goods, unidentifiable lost property or leaked confidential marks? This invisible marker is your perfect solution! It uses professional UV-reactive ink to leave hidden marks that only appear under ultraviolet light, ideal for anti-counterfeit verification, confidential marking and property identification.## Key Features1. UV-Reactive Invisible Ink: The specially formulated UV-sensitive fluorescent ink stays fully transparent and unnoticeable under regular natural light, and glows bright clear fluorescent light under UV irradiation. You can leave confidential anti-counterfeit marks or private labels that will not be spotted by irrelevant personnel, effectively protecting your property security and preventing product counterfeiting.2. Dual-Tip Design: It comes with 2 wear-resistant fiber nibs (1 broad tip + 1 fine tip) paired with a sturdy crack-resistant ABS pen body. It supports both fast large-area marking and precise detailed marking, fully meeting different marking demands across multiple scenarios.3. Waterproof & Quick-Dry: Adopting water-resistant fast-curing ink, it dries completely within 3 seconds after writing with no smudging. The marks will not blur or wash off when exposed to water, ensuring long-lasting stable marking performance even in humid environments.4. High Adhesion & Fade-Resistant: The high-penetration high-adhesion ink has strong covering power, adheres firmly to most common surfaces including paper, plastic, product packaging, leather and glass. The marks are not easy to scrape or wipe off, remaining clearly visible under UV light for a long service life.5. Safe Non-Toxic Material: Made of eco-friendly non-irritating ink and food-grade safe ABS pen body, it contains no harmful heavy metals or irritating components.
