The Elgydium Clinic Trio Compact Mic Fine-123 is a professional interdental brush set designed for thorough cleaning between teeth. This compact set features specialized brushes with different sizes for effective plaque removal and optimal oral hygiene. As this is a personal hygiene product (interdental brushes), I have kept the key features list empty per the requirements. The product appears to be manufactured by Pierre Fabre Oral Care and comes with professional technology for interdental cleaning.
