We've tested these with our Kinder lunches and the ice packs were still cold after 8 yours in the Australian heat! Here at Ast + Co, we love that the self-contained gel ice pack has been independently certified “food safe”. It comes in its own cosy black cover and fits like a dream in our cool bags.
These fit perfectly into our lunchbags
Ice Pack Measurements: 26cm x 17.5cm x 1cm
