- 5 Packs Reusable Ice Packs for Lunch Boxes - 12+ Hour Cooling Ice Gel Pack for Camping, Beach, Office - Ice Packs for Cooler Bag, Cooler Backpacks

These stay cold ALL day! Love these for my kinder kiddo! We use with an under armour lunch bag and lunchbots stainless steel bentos. I pack his lunch at 630/7 am and when I unpack his empty stuff at 330 the center of the ice pack is still frozen. Haven't had a leak or puncture, they are a good size though a bit heavy.

held up really well, stay cold

Thin enough to fit multiple in my work lunchbox and to store in the freezer! Stays frozen for quite a while but I’m in AZ, it won’t stay frozen all day, but I don’t expect it to.

I hardly ever review the things I buy on Amazon but felt compelled to rate this. I am a nurse and work 12 hour shifts. Our fridge is too small too hold everyone’s meals each shift, so I was looking for ice packs that would keep my lunch cold in an insulated tote stored in my locker. These ice packs are amazing - I pack my lunch at 6:15PM and get home around 8:00AM, and my ice packs are still frozen and any remaining items in my tote are still ice cold. I’m so impressed by this product. Strongly recommend!

These lunch freezer packs have held up in my plastic work bag I bring with me for lunch everyday. I put 2 in with my water and food snacks, after 8 hours I come home and unpack it and they are just getting thawed. Not bad for what I use them for, and the price was just right too.

The best ice packs! I’ve had them for a while and gets you through an 8 hour shift. Does melt but sometimes I come home and the middle is still iced. Works well! Size is amazing.

Love these! Stay frozen all day in lunchbox. Easy to wipe clean. Compact and don’t take too much room in lunchbox.

These work great! They last all day in my son's lunch box. They are thin enough not to cause excess bulk and fit nicely in the smaller inside zipper. Highly recommend, especially if you have a kid who prefers to bring a lunch from home.
