Our BNC Thermogel blackholesun No. 7 4ml is a state-of-the-art nail gel that offers impressive color-changing effects thanks to its thermo-sensitive properties. Applied to the prepared nail, the gel enables optimal results and a dynamic color change when the temperature changes thanks to a thin, even layer. For a more intense color effect, a second layer can be applied and cured again. Finally, the gel is sealed with a sealing gel that provides long-lasting shine and protection. Perfect for creating eye-catching and individual nail art that changes with your surroundings. Ideal for professional use in nail salons or for DIY manicures at home.
