Borosilicate contains boric oxide, which makes it even more resistant to thermal shock than tempered glass, but it’s also more expensive to produce. The lids are plastic and can be used in the freezer, though we found that they're not quite microwave safe, despite being advertised as such.

The Bentgo Kids is an innovative lunch box which was designed for active children who do a lot of travelling. Cleaning is easy in the dishwasher or by hand, but food can get stuck in the crevices of the lids, so it's best not to overfill the containers in the first place. Excellent/smooth transaction; the item was purchased at a very good cost, the seller’s communication was great, the description of the item was accurate, and it was delivered super fast. I plan the lunches with my kids, but I have help packing them and will help so much with communicating what goes where and without my silly drawing of them every week!Read our editorial process to learn more about how we fact-check and keep our content accurate, reliable, and trustworthy. They are simple to clean in the dishwasher or by hand thanks to their rounded edges, and the soft silicone gives the containers a better grip. However, this is to be expected out of glass construction, and it was an easy enough fix to use a pot holder. It’s also great for making a full tray of mac and cheese and marinating meats before they meet the grill and for storing leftovers without moving the food to a different container.

If your glass container doesn’t say it’s tempered or strengthened, it’s probably untreated or just regular old glass.they could've made the design better as to make each compartment bigger (the small circle literally doesn't fit anything but nuts or gummies). We were pleased to discover that these containers distribute heat evenly in the oven and the microwave (we reheated a casserole and found no hot or cool spots). The containers are very easy to clean thanks to the rounded inner corners, which remove any nooks and crannies where food might otherwise get trapped. It's another Bentgo-style lunch box brand that manufactures products that are not just practical but also visually appealing.
