Healthy Packers Reusable Ice Packs for Lunch Boxes - Long Lasting Slim Freezer Packs, Thin Non-Toxic BPA-Free Hard Gel Ice Blocks for Coolers, Kids & Adults Lunch Bags, Travel, Camping, Food Storage

Slim sized, versatile. Thin enough to fit in children's lunch-packs. These freeze fast and have the trusty hole design that slows down thaw time (somehow, bcuz it's physics). Keep food cooler longer in fridge or freezer fridge if the lights go out. Extends ice life and since they're Non-toxic, when it finally does melt, water is still safe to drink No one should be without a quality cooler and alot of these ice packs. Take them on a weekend hike or just gone fishing. I've not experienced any leaking or defects with Healthy Packers brand. They are really affordable, durable a worthwhile investment. Wash them with mild soapy water in sink, dry off and freeze

Great little icepacks!

Perfect for lunch boxes! Have been using for about a month now and it is still cool when I take it out of lunch box 10hrs later.

I’m not sure these are large enough for my backpack cooler… they don’t seem to do much to keep things cool… but my cooler may be too large for these and they should be used for a lunch box.

good no complaints fits in lunch box well and much better than our old ones

Keep my food so cold in my lunch bag I love it

It does what it’s supposed to do. I’m happy with that

Durable. Slim design makes them easy to fit in small coolers or lunchboxes. They don’t stay frozen for a full day—more like 3 hrs
