Sometimes the clutter gets a little too much. Maybe you're used to the "creative mess," and you don't mind a little "personality" in your space. Yet, before long you start getting antsy. You're strangely tense, like something's eating away at you, and you can't identify what exactly. You're more irritable than usual. But who likes tidying up? Each box of extra large resealable plastic bags contains 12 extra large space saver bags that measure 18 inch x 24 inch large - so around the size of a large cookie sheet - and 2mm thick, so you can trust that it'll take quite the load to rip these resealable baggies. They're made of sturdy and waterproof LPDE, which you can write on with a marker - just don't leave the ink on for too long or it may never get off. Each of these resealable zipper bags are BPA-free and food safe - so you can stick them in the freezer when you need to store a bunch of meat or fish - but they are not for cooking, so don't accidentally use these freezer storage bags for your sous vide. Since they're so clear, with no markings on them, you can see straight through the extra large food storage bags, which makes your life so much easier (and much more organized). The uses for these heavy duty clear storage bags are limitless. They're great as extra large food storage bags, or as freezer storage bags. Use the large see through plastic bags to keep the kids' messes more manageable. They're a great companion when transporting, storing, packing, and moving things. It definitely doesn't hurt to keep a well-organized house! The Clearware sealable plastic sleeves are a fantastic solution to life's little messes. Grab a box of these 5 gallon freezer bags!
