Promising review: "If you're looking for a set of reusable bags to reduce your waste, look no further. This Zip Top silicone set is just about perfect. The eight-piece full set comes with cups (with circular flat bottoms), dishes (with elongated flat bottoms) and bags (for easy taking to-go without taking up a bunch of room). They're airtight, and just EASY PEASY to use — aka I don't have to track down a matching lid. Half-eaten oranges, leftover crepe batter, granola, all live handily in these pretty lavender containers. The pointed sides make for effortless pouring — everything from shaking granola into my morning yogurt to dispensing thin crepe batter into a pan for a weekend breakfast.
They're dishwasher-safe (on the top AND bottom racks), freezer-safe, AND microwave safe, so you can truly say goodbye forever to disposable bags. They haven't retained any sorts of staining or smells and wash up beautifully. At just over $11 a pop when you break it down, they're not *cheap* but when you add up box after box after box of plastic bags, you'll make up for the cost in no time flat. I haven't been ~on the go~ much in the past year (🙃), but when I do I'll definitely use these to bring snacks to the office. And they come in pretty pastel colors that personally just make me happy to look at in my fridge." —Maitland Quitmeyer, BuzzFeed Deputy Editor
