ถุงร้อนเย็นอะโวคาโด

I wasn't sure a frozen avocado could actually keep my salad crisp, but after a morning in the freezer it stayed cold through lunch. The heat-and-freeze versatility is perfect for my small lunch bag, and the shape is way more fun than a boring old ice pack.

Heating this up for my lunch leftovers was surprisingly easy—just a few minutes in hot water did the trick. The fun avocado shape actually makes it stand out in the freezer, and it kept my soup warm for over an hour.

The shape is so cute that my coworkers always comment on it, and it actually keeps my soup hot for a solid couple of hours. I just pop it in boiling water before I leave and it's ready to go.
