"I love these glass containers! I use these for my leftovers to take lunch to work, for extra dressings, or to keep my extra ground coffee/espresso fresh.
There's just something about glass that seems so much nicer than plastic tupperware.
They are dishwasher safe. I put the lids on the top rack and haven't had any problems getting them retain the same shape for a tight fit on the container.
I also really like that out of all the containers I have the lids on these fit the best so that I'm not nervous to carry my leftover soup in my bag on the way to work in the morning. I've never had a spill.
I would rather use these over anything else in my tupperware cabinet and consider them a kitchen essential now. They are a best buy."
