Made from 100% cotton and a blend of beeswax and essential oils, this set of two reusable sandwich bags offers a practical alternative to plastic and foil wraps and is naturally anti-bacterial. The unbleached cotton is printed with food-safe soy ink before being infused with beeswax and oils sourced from carefully managed hives. To use, gently warm the bag in your hands, place your food inside, and hold it closed. As the bag cools, it moulds to seal your food securely. (Not suitable for raw meat and fish.) When the wax coating wears down and the bag becomes less sticky, you can refresh it using Natural Elements Bee's Wax Refresh Cubes, available separately (NEBWAXCUBE12PC). Combining practicality and style, the Natural Elements range embraces natural materials for kitchen use, bringing a unique feel to your home and helping to reduce plastic, especially single-use products.
