These glass storage bowls are great! After years of using plastic storage containers that retain smells and stains even after thorough washings, these bowls are a welcome relief. I have kept curries and marinara sauces in these bowls, and have never had the problems with stains and smells that I had with plastic containers. These bowls are safe for the microwave and oven (though they can get too hot to handle with bare hands), which is very convenient along with the fact that they are also dishwasher safe. I still have disposable plastic containers to send leftovers home with guests, however I have replaced all of my regular hard plastic containers with these glass ones, because they are just so much better!
I recommend this product.
