MAVA-STRONG is a fortifying and protective base coat for nails from Mavala Switzerland. This 10ml nail treatment is designed to strengthen weak nails while providing a protective base layer before nail polish application. The product comes in a 10ml/.3 fl. oz bottle with a precision brush applicator. As a base coat, it should be applied directly to clean, bare nails before regular nail polish. Being a personal nail care product, it's recommended to avoid sharing the applicator with others for hygiene purposes.
