Mavala Flex Serum is a specialized nail care treatment designed specifically for dry and excessively hard nails. This Swiss-made serum helps restore flexibility and moisture to brittle nails, making them less prone to breaking and splitting. The product comes in a 10ml/.3 fl. oz bottle with an applicator brush for easy use. As a personal care product from Mavala Switzerland's nail care line, this serum focuses on treating and improving nail health rather than cosmetic purposes.
