Lock & Lock Glass containers, the original oven safe containers, are essential when it comes to storing, re-heating or even cooking your food.
Each piece (container and lid) is freezer, dishwasher and microwave
safe. The borosilicate glass container also goes in the oven up to 750F /
400C. They are the perfect practical solution for bringing your lunch,
storing your leftovers, or to use from the oven to the table!
These break in the oven. I used them several times for all sort of things, and on 2 occasions they broke. I had the oven at 375C. They were great for using in the fridge, freeze, microwave etc, but don't use it in the oven.
