Proto Future’s eco-friendly laundry detergent strips are a type of laundry detergent that come in the form of thin, paper-like sheets or small strips. One sheet is made up out of two strips. One strip is designed to be the perfect dosage for a regular wash, and two (or one sheet) is suitable for a large wash or to combat any particularly stubborn stains. They are made from biodegradable and plant-based ingredients and are a convenient and an eco-friendly alternative to traditional liquid or powder laundry detergent.
