Our 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.
Ice Pack Measurements: 26cm x 17.5cm x 1cm
Freeze the cooling panel WITHOUT the ice pack cover. Air the ice pack cover overnight to allow it to thoroughly dry before using it the next day.
Keeps the contents of the lunch box cold all day. Only very minimal melting of the gel even on super hot days (45 degree) and my sons lunch box is kept outside under the verandah at school out in the heat.
