Small habits add up to big changes. Think how many single-use plastic bags this one can save. The original stand-up quart/4-cup (re)zip is kind of like the quart bags you know, but better, because they are tougher, stronger, and safer. Made from 100% food-safe PEVA, they are lightweight (not floppy) and stand on their own sturdy base so they’re easy to fill and clean. Their double-lock closure makes them leakproof and airtight. This stellar ability to keep liquids in and lock air out made them the #1 choice in America's Test Kitchen reusable bag test. Bag Details: - Bag dimensions: 9.5 in x 2.5 in x 6.5 in - BPA-free, lead-free, and phthalate-free - Smooth, durable, and lightweight - Stands on its own: easy to fill - Saves hundreds of disposable plastic bags - Airtight, waterproof, and leakproof - Resealable double zip “clicks” shut (mmm satisfying) - Freezer safe: perfect for storing stock, soup, and vegetables
