Great half pint wide mouth jar

Love these 8 oz jars for canning. They are wide mouth and unique shape. Easy to fill and have fill marks on the side. Also, I've not had a lid fail to seal.

Right size Right price

Good value for generic item. Ran the jars, not lids, through dishwasher with no issue.

Cute canning and storage jars

These jars are super cute and the perfect size I needed for homemade jam. I had a few jars that didn't seal when I water bath canned: not sure if it was an issue with these lids or an issue on my end
