Large white silicone stand up bag 21x24 cm special to buy in bulk, store food and as a toiletry bag. With base to stand. This bag is an innovative, ecological and healthy alternative to plastic. The Stasher bag is reusable and thanks to its safe material, the totally hermetic seal and the base to stand up, it becomes a multipurpose bag, which allows us to transport food and objects to work, school, travel, etc. Ideal for transporting nuts, a piece of cut fruit, some cookies, a sandwich, use as a toiletry bag to store toothbrushes, moisturizer, sunscreen, makeup, etc. It is recommended to cook in the microwave and not to close the bag. In the oven with a papillote and in a bain-marie or using the sous-vide technique (cook by immersing the closed bag in hot water at a low temperature). These are techniques that we have never recommended using with plastic bags, but that we can do with these platinum silicone bags. Wash well after each use with soap and water. Keep and store food in the pantry, in the fridge or in the freezer. It closes hermetically only by pressing firmly on the edges. For better preservation of food and for it to take up less volume, extract the air from inside the bag before closing it.
