⚠️ Attention! To avoid unwanted polymerization of the material during work, testing, or content recording, open jars or brushes should be kept as far away from daylight as possible (especially direct sunlight). Please note that even on cloudy days, clouds allow a large amount of ultraviolet radiation to pass through, which is sufficient for material polymerization. When painting tips, we recommend that the working side of the UV lamp faces away from the nail technician. If the lit lamp faces the technician, unwanted polymerization of the material on brushes and at the necks of open jars may occur.
