It combines the cutting and sealing functions into one, so you can easily open and close packages with just one device. This bag heat sealer works with a wide variety of chips, cookies, cereal, candy, bread, pet food, food bags, Mylar bags and plastic bags - but not for thin food storage bags. It comes with a 400mAh rechargeable battery and mini USB cable for more powerful and environmentally friendly use than traditional AA battery models. At only 0.2 pounds in weight, this mini bag sealer is ultra-lightweight and easy to carry around outdoors for picnics or camping trips to ensure the outdoor food remains fresh. Additionally, it has a magnet on the back so it can be attached to your refrigerator for convenient use when in the kitchen.
