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

These are great. Stayed cold for over 8 hours to bring to an appointment where I needed to have items frozen. These were great! Know you might need gloves to touch them so you don’t get freezer burns. I used gloves and it worked well.

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.

These ice packs are fantastic for keeping lunches fresh all day—especially great for school bags, picnics, or grocery runs. The durable, flat design and long-lasting chill make them a smart value choice. Just be sure to choose the size that fits your needs and give them plenty of freezer time.

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.
