Little Chill Pack

"Keep the kids' lunch cool as a cucumber with this handy chill pack. Certified food safe, this little pack of chill will ensure lunch stays fresh and crisp (and eaten!). The slip-on cover is machine-washable and it fits snug as a bug in the Little Cooler Lunch Bag - a match made in heaven!
Buy on its own or bundle up and save with the Little Cooler Lunch Bag + Chill combo pack! Or buy on its own as a spare so you've always got one frozen and ready to go."

"Your Little Chill Pack likes leaving its fabric cover on to keep it safe and reduce condensation when it sits in your lunch bag.
Though when it's in the freezer, it likes to go nude and to lie flat. Once it comes out of the freezer, pop its cover back on. This will make sure lunch stays fresh
If your cover becomes icy or wet, air it out until it's 100% dry, as otherwise this could dampen your lunch bag - and no one wants a soggy sandwich!
Your cover is machine washable, simply pop it in the washing machine and hang it out to dry!"
