Each bar is roughly 4oz. They are handmade with all natural ingredients, essential oils, and goat milk from our very own goats here at Maple Leaf Farm & Creamery in Michigan. Goat Milk has many great healing properties for your skin, including anti-aging properties, it restores your skin's natural barrier with antioxidants such as vitamin C & E, and it exfoliates away dead skin cells that are a common cause of fine lines and wrinkles.
