These reusable ice packs are really convenient if you pack lunches that need to stay cool. I keep them in the freezer and just add one to a lunch box with things like yogurt or cheese. The slim design fits easily alongside food, and when the lunch bag comes home I just put the ice pack back in the freezer so it’s ready again for the next day. LTKmomlife LTKKids
