Are these freezer safe or do you have any freezer safe glass jars?

Flint glass, or soda-lime glass, is generally not considered safe for freezing as it may break due to rapid temperature changes. Glass can be prone to shattering when exposed to extreme cold. For freezer storage, it is recommended to use glassware labeled as freezer-safe or opt for materials like borosilicate glass, which is more resistant to thermal shock
