describe
- From bulk to brilliance. Ditch the seepage and the stress—welcome a new era of sleek, high-precision nail extensions with perfectly apexed enhancements every single time.
- Our patented sandwich structure uses a Top Mold + Bottom Mold to press-fit the nail extension, creating a seamless and controlled nail extension with minimal gel overflow. It helps achieve a cleaner C-curve and perfect symmetry, and is less likely to cause gel overflow than paper forms or traditional dual forms. The application is cleaner, requires less adjustment, shortens service time, improves service quality, and delivers a flawless, smooth finish every time.
New Arrivals — Three All-New Patented Types
- Patented Ergonomic "Spoon" Design & Anti-Glare Matte Surface (W561 / W560 / W556):The spoon-style handle makes the top mold easier and more stable to hold, gives you a clearer working view, and improves placement control during application. The matte surface helps reduce visual glare under salon lighting, making it easier to judge gel quantity, apex placement, and symmetry with more precision.
- New patented spoon-shaped top film (W558/W559): The top film has a "handle" like a spoon, making it more stable to hold with your fingers. It doesn't obstruct your view during operation, allowing you to easily observe the amount and position of gel, and it's easier for beginners to control.
- More stable bottom film: The upgraded bottom structure prevents it from easily loosening or falling off during the extension process, maintaining the stable extended shape.
- New scale line design: The scale is clearly visible, making it easy to understand the length and effect of each extension at a glance, facilitating the creation of equal finger lengths and replicating the same length during follow-up visits.
- Professional packaging & reusable: 8 pieces/compartment × 30 compartments = 240 pieces/box. High durability, can be reused multiple times after proper disinfection, meeting the workload of high-traffic salons and professional nail technicians.
