Bentgo アイスパック4個セット 冷凍食保存用 超薄型 ブルー na

These freeze up well overnight. They serve their purpose to keep my kids lunches cold until lunch time. They are thin so they don't take up too much room in the lunch kit and they are fairly light so they don't add a ton of weight either. I have a few packs because we throw them in a cooler or golf bag too!

muy buen producto y enfría muy bien

I bought these cause they werent thick and would fit perfectly my small lunch box :)!!! Its really great. After 8hs it was still a bit frozen, so if your lunch is 4hs into work your food will be cold still

They stay cold a long time and are a nice thin size so not too heavy and thick.

They work. This year my kiddo has recess first then lunch so they take their packed lunches outside to sit in the sun for 20-ish minutes. That really did a number on kiddo’s lunch so I got these to keep everything cold. Kid says everything tastes and feels great again so they must last a good while too. They’re not dishwasher safe but they’re easy to clean and in fact my kid cleans them on their own.
