Stash everything! Cook it, freeze it, store it in a Stasher Bag. Made from pure silicone, this is the healthier alternative to plastic. The airtight seal locks in liquids, flavor and nutrients. It moves from fridge and freezer to stovetop, sous vide and oven. Use it for lunch, to keep your cell phone dry, to freeze leftovers. The possibilities are many as the bags are usable over and over. Dishwasher safe for cleaning. Available in small (snack) 9.9 oz/293ml , medium (sandwich)15 oz/450ml and large (cooking)64.2 oz/1.92L sizes.
