Magic Brush Nature, now in an environmentally improved plastic made from 50% plant-based materials such as straw and sugar. The plastic in the brush is also 100% biodegradable. Nature is a new medium-hard version of Magic Brush's popular brushes, making it the perfect addition for those who already own the Original and Soft versions in their grooming box. As with the other Magic Brush plastic brushes, Nature effectively removes dirt and mud and is perfect for when the horse is shedding out. The brush can be washed at 60 degrees in the washing machine when it gets dirty.
