Possibly the most versatile of the Stasher bag lineup, the stand-up bag is endlessly reusable and useful in the kitchen and beyond. Perfect for bulk shopping, storing leftovers and soups, and marinating meat and veggies, the stand-up folds flat when not inure for ultimate portability and space-saving. This non-toxic bag is made of pure platinum food-grade silicone and is sous-vide, microwave, dishwasher, and freezer safe. Its patented Pinch-Loc® seal also makes it an ideal makeup or personal care product container, especially on the go. Stasher is proud to donate 1% of proceeds to environmental nonprofits working to protect the planet. By joining Stasher's Save What Matters movement, you can help keep millions of single-use plastics out of our oceans.
