Vacuum Insulated Food Jar
This double-walled, stainless steel food jar from Thermos ($21) will be the superhero of your lunchbox, keeping both hot and chilled foods at their respective temperatures for 5-7 hours. Of course, the colorful designs don’t hurt either (there are two to choose from). Its ergonomic and leak proof lid is also easy for little ones to open, so you have one less worry at lunchtime.
- Dishwasher-safe (top rack only)
