TOURIT Reusable Ice Packs - Long Lasting Freezer Packs for Lunch Bags, Boxes, Backpacks (Set of 4)

4-Pack Ice Packs: Reusable and versatile cooler packs. Each ice pack measures 9.75"" x 9.75"" x 1"". Colder than ice at 18° F (-8° C) to keep your food and drinks cold for longer!. Lasting Long: We use a powerful gel-filled ice pack rather than standard water to keep us cold for longer. Additionally, we use insulation that is more resistant to wear, making our gel ice packs reusable and more long-lasting. Reusable & Safe: These lightweight and portable freezer packs are made with 100% BPA-FREE, non-toxic materials. Easy to clean and reusable, great replacement for traditional ice cubes. Easy to use: Simply add water once, don't bother changing the water over and again, before first use, utilize the included funnel to add water once, shake well, screw on the lid, and then freeze until prepared to utilize is okay. Keep Chilled On The Go: These ice packs will keep your food and drinks chilled when you don’t have access to a refrigerator. Great for freezer-to-lunch bag trips or any occasion - lunch bags, cooler backpacks, breast milk bags, work, or outdoor camping
