Iris toilet brush from Iris Hantverk combines oiled birch and synthetic fibre, with a cup made of handcrafted smooth concrete from Tyresö. The smooth concrete, with its polymer-based elasticity, provides a pleasant feel to the touch without compromising strength. The material is free from environmentally harmful substances and may have natural colour variations for a dynamic appearance. The brush is easy to maintain; rinse it after use for freshness. The soft surface and unique craftsmanship make this toilet brush both functional and durable.
