Go nuts with Eco Nuts Organic Laundry Soap. Composed of dried organic berries sourced from the Himalayas, these reusable "nuts" contain a natural detergent that suds up when mixed with water. Since they are certified USDA organic and reusable up to 10 times, Eco Nuts are both environmentally sound and wallet friendly. Simply place 4-5 berries in the provided cloth bag and toss in the wash for fresh, clean laundry without the harsh chemicals or fragrances of conventional soaps. Not only are they a safe alternative for those with sensitive skin and/or nut allergies, each cardboard box replaces at least one plastic bottle which will never wind up in a landfill.
