Bought these to go with my medium straight sided jars and they are perfect. Haven't had any issues with them popping off on sitting crooked. Definitely recommend.

Bought those to for tureen 3oz jars, fits perfectly, looks great too.

exactly whats pictured. doesnt fit the medium straight sided jar perfectly but it does stay on.

I ordered the lids advertised for my jars and while they look nice, they don't fit. They sit on the top of the jar at an angle and pop off extremely easily. I'm very disappointed and would recommend you don't purchase these lids if you expect them to fit.
