Brighten up your lunch! This colorful set of four reusable ice packs are slim enough to fit into a fully packed bag, yet mighty enough to keep food and drinks cold for hours! Great for a variety of uses: pack in your lunch bag, beach tote, sports cooler, and much more! For best results, freeze overnight and stack several ice packs around the sides/top of your insulated bag to maximize cooling power. The BPA-free ice packs are non-toxic and safe to pack with unpackaged food. The fun and vibrant colors add a little extra pizazz to your insulated bag, tote, or cooler!
