JL Childress’ 8oz Reusable Ice Packs are the coolest accessory for use in any insulated container! These Reusable Ice Packs freeze SOLID, staying frozen longer than flexible ice packs and keeping your food and drinks cool and fresh for hours. They easily fit into insulated bottle bags, lunch bags and breast milk coolers and can also be used inside hard-sided coolers of any shape and size. When ice packs thaw, simply place back into freezer for use over and over again from the bottle stage to the sitting-at-a-baseball-field-for-hours-in-the-sun stage and everything in between! JL Childress’ Reusable Ice Packs are food safe, non-toxic and durable. Always keep extras in the freezer so you\'re ready to go any day, any time!
