Klean Shop Jam Jars With Lids – Red/Blue Lid Jam Jar Set – Fruit Mason Jar – Glass Jam Canning Jars – DIY 2oz (80ml), 24 Pack Jars- Perfect for Jam Storing, Pickles and Many Other

These jars work very nicely. I was making jam as party favors for 80 people for a 90th birthday celebration and wanted jars that were more substantial than a 1-1.5 ounce without using a full sized 4 ounce canning jar. They were overall nicely made, sealed well, held up in the boiling water bath sealing process and looked great. The reasons I couldn't give 5 stars: (1) 2 jars (out of the 4 cases I purchased) had imperfections in the rim of the glass and couldn't be used as the glass would not contact the sealing surface. (2) An additional 2 jars did not seal properly... but hey... as another reviewer pointed out - more jam for me! (3) They were NOT 2 ounce jars. They were 3+ which meant I needed to make one more batch of jam than I was planning. So if you are looking for 2 ounce... these are bigger than you want. In the final analysis I loved the jars and would consider buying them again.

Excellent
