Q: Are glass containers microwave safe?
A: Yes, remove the lid first — the glass is microwave safe, the plastic lid is not.
Q: Will they break in the freezer?
A: Borosilicate glass handles freezer temps well; just leave headspace for liquids since they expand when frozen.
Q: How many containers do I need for a week?
A: Most people find 5-7 containers cover a standard week, which is why a 10-piece mixed-size set works well.
