Simply warm them in your hands and wrap them around produce, bowls, sandwiches, nuts, snacks, cheese and cooked / smoked meats - virtually any perishable. The wraps stick to themselves and provide a clean and protective seal. They cool and cure almost instantly.
After use, simply rinse in cold water - hot water will reduce the wax coating - and wash with an eco-friendly soap (avoid alcohol based soaps), just like you would a plate or bowl. Once clean you can either hang to dry or use a towel and re-use immediately. They may - with certain foods like pomegranate - develop a darker patina, but as long as you keep working them they'll keep delivering freshness.
All of our dyes are non toxic and free of heavy metals, AZOs and formaldehyde found in typical textile dyes. We use a Certified Organic cotton fabric. Both the dyes and the fabric utilize very little water to be processed, of which a great portion is recycled. They are certified under the Global Organic Textile Standard - recognized as the world's leading processing standard for textiles made from organic fibres - which means they are also in compliance with social criteria.
