These hard ice packs look like popsicles, but they're actually ice packs. They come in three fun colors: blue, red, and glow-in-the-dark. If frozen for more than eight hours, they'll stay cold for about 4.5 hours. They keep your side dishes at the right temperature without freezing them, preserving their texture and preventing changes in flavor. Simply having one in your lunch box will add a special touch to your everyday bento.
