The size is great for salads and leftovers and the lid seals nicely. I love these types of containers!

Love this bowl with a sealing lid. Perfect for leftover

OXO has to be my favorite brand. Theresa storage containers are so great. You don’t need a jackhammer to get the kids off and it seals wonderfully.

[This review was collected as part of a promotion.] These Smart Seal glass containers are made from borosilicate glass which is stronger and less prone to thermal shock than the regular glass containers made from soda lime like newer Pyrex and Glasslock brands are. We have had too many Glasslocks break and shatter all over the place under normal usage conditions so we switched to Oxo and got rid of all the other brands we had. The one thing that could be improved with Oxo glassware is the lids are sometimes difficult to get on.

Good quality. Only complaint is the average size is a bit small.
