Unbreakable and microwaveable
These are our casual daily cereal and soup bowls --- excellent quality, an improvement over plastic that's less viable for re-heating in microwave.  They will stain with red sauce etc., but so will anything other than glass or ceramic, and the staining's less than with some plastics. For children or older folks who tend to drop things, the unbreakable feature is excellent.
