With everything you put into healthy food choices a more thoughtful storage bag only makes sense. Easy to use, easy to clean, reusable and non-toxic, Stasher bags fit you perfectly. Stasher can take the heat, the cold, and anything else your kitchen dishes out. Thanks to the patented airtight seal, all of your food's nutrients, flavors and juices stay locked in. Stasher can defrost or cook food in minutes. Tip: Just leave bag open and place in microwave. Oven: Place on oven-safe pan directly in oven, leave seal open. Sous vide: Fill Stasher bag, do not seal. Slowly lower into water, allow air to escape and vacuum to form around contents before sealing. Place in upper rack for best results or hand wash with soap + warm water. Freezer safe and ideal for food storage. Stasher lets you make meals ahead of time and easily store whatever's leftover. Tip: Use dry erase markers to label contents.
