Add a serving of miso soup or another soup to your usual bento with this 400 ml (13.5 fl oz) vacuum-insulated food jar. The vacuum structure keeps contents hot or cold until lunchtime, so food stays closer to its ideal eating temperature. Heat retention keeps contents above 63°C (145°F), and cold retention keeps contents below 11°C (52°F), for up to 6 hours.
The wide opening, about 63 mm (2.5 in) across, makes it easy to fill and simple to clean after use. Besides soup, the jar also works well for holding fruit or other desserts. This version comes in dark brown.
