Features 1. One step three effect design: This nail polish pen combines base oil, gel color oil and seal oil into one, eliminating additional products and complicated application steps - just rotate the pen cover, apply nails, and cure under the ultraviolet light. The versatile formula makes nail care faster and easier, allowing both beginners and experts to easily achieve professional level results. 2. Easy stain free application: fast drying UV gel can be easily squeezed out by continuously rotating the pen holder in one direction - zero stain, zero waste. Do not rotate repeatedly to avoid blockage or malfunction. The soaking formula only takes 60-90 seconds to cure under UV or LED light, presenting a long-lasting and anti peeling glossy texture, making perfect nail art more time-saving. 3. Quick drying gel formula: advanced quick drying formula shortens waiting time and improves nail enhancement efficiency. Unlike ordinary nail polish, this gel can be completely dried in a few minutes under ultraviolet radiation. No need to worry about smudging or dents - your nails will remain perfect for a long time and you can immediately engage in daily activities. Perfect fit for fast-paced life. 4. High color rendering coverage: each pen core contains high concentration gel, which can be fully covered by single layer application. After curing, the color is long-lasting, bright, and glossy, eliminating stripes and mottled phenomena. Single layer presents a light and elegant makeup effect, while layered application creates a strong dramatic feeling that lasts for a long time without fading. 5. No bottom oil design: eliminates the bottom oil step and saves time - the intelligent one-steps formula can be directly combined with the nail surface. Even without the bottom treatment, nail polish can still be applied smoothly and firmly without falling off. Perfectly meet the needs of fast nail art, balancing durability and gloss.
