ecozoiStainless Steel Lunch Chillers - Ice Packs for Lunch Bags, Lunch Boxes, Bento Boxes and Coolers - 2 Pack, Plastic-Free and Sustainable

UPDATE: I've bought this product multiple times as it works well. I've been in a position where these freezer packs were just wrapped in towels and placed in carry on luggage (not an insulated case). The portable oxygen concentrator for my travel companion overheated mid flight. These packs were still frozen and we managed to get the device cooled down within 5-10 mins. I put one back into the back of the concentrator bag (and it fit snuggly being so thin). It completely thawed out by the time we touched down, which is so impressive because the machine was quite warm for the rest of the flight. Still 5/5 stars, it's keeps frozen extra long!---------------5/5 stars: It works exactly as designed, and it's very thin. I worry when it's thawed it may be easier to dent the product (something to keep in mind if there is a chance it will be tossed around when thawed). It seems to stay cold extra long because of the metal casing. Only negative is it is heavy. It being so thin means we can put more things in our cooler. I've already bought this product multiple times because I like it so much.

I am very pleased with this purchase. These are great alternatives to those plastic ice packs that take up so much more space. My daughter likes to take a fruit shake as a mid morning snack for school and these are super helpful to keep it cold for her to enjoy. These look great, freeze faster than the plastic ones and it is a nice eco friendly option. Definitely recommend this product !

I got these as an eco-friendly ice pack option in my preschooler’s lunch box. I like that they are thin so they don’t take up a lot of space in her small lunch box. Definitely recommend.

I love these stainless steel ice packs. They keep cold for several hours and keep my food cold. I love how thin they are so that they don’t take up too much space in my lunch box. Great eco friendly option.

Everyday lunch.

Love these! They’re slim and stay cold. Was sick of leaky plastic ice packs with questionable gel goo in the center. These work great. It has been super hot here the past few weeks. We always take these with us for our cooler bags when we grocery shop. Would love it if this company made bigger ones too.

I really wanted to love these which is why I paid $27 for them. I needed an option that will keep things cold in my office at work. These however thawed within an hour and didn't keep the food cold. For example, I froze them today at 2p and they are already unthawed and warm by 5p. They were stored in a YETI cooler. I would not recommend purchasing these.

These are of great quality, worth the value. They match well with my bento box and have a nice, contemporary look.

Great alternative to plastic ice packs and super thin. These keep my sons lunches nice and cold from 8 a.m. to 12 p.m. and are fully thawed by the time that he gets home. They freeze way faster than the thick plastic ones and leave plenty of space in the lunch kit.
