Poor design. Don't buy.
on June 5, 2012
Lids are hard to seal and tell if they are sealed. Jars collapse when putting lid on. Ball makes a similar, but MUCH better plastic jar with a screw-on lid.
The lids are very hard to attach. You often have to push so hard that the plastic jar collapses making for quite a mess. It is also hard to tell if the lid is actually in place. The top is made of a rather soft plastic. Therefore, it slides input place rather than snaps. That is part of the reason why it is hard to tell if it is all the way sealed.
I filled to ½ inch from the top. I put it in the freezer. Some of the lids came unsealed. I'm not sure why - it was not due to over-filling.
They do stack nicely. I like the plastic the lid is made out of. It seem like it would last a long time. However, it does not seal very good (as stated above). The cups look nice. However, due to the shape, they collapse easily when putting the lid on. If you look at the picture, you can kind of see the bend in the jar where it would tend to collapse.
These were now so I purchased them. Ball has some similar jars they have been selling. I purchased them after these. They are MUCH better. The tops screw on snug. The tops screw to the bottom of the next jar and to themselves. This helps with storage when they are full and empty. Great idea. But again, this is for the other jars.
