I buy my bowls, and food storage containers from this company always. I have the taller ones already but needed the smaller ones, I make a lot of smaller meals in the winter. This is perfect, to hold hot and cold food, and is easy for the microwave.
I am from NYC, and all the Chinese restaurants use these for soups and tea. Yes, tea, I do the same with mine, I add my drinks and on top of the lid I make an X with a knife and add my straw. I am prone to spilling things, so this is not just convenient, but nostalgic.
