EXACTLY what I was looking for!

This is a great product for any kitchen. I love the caps over the lids that help for moist humid climates in keeping my salts and homemade spice mixes dry. They fit the mouth of Ball and Kerr jars perfectly while you choose the container size to fit your needs. It also helps with the control of seasonings. This is my first set and highly recommend these lids. I find the holes too large for dusting flours and powdered sugar (I still use a fine strainer) but that is just my preference. They are also very handy for a person with many rubs or mixes, being able to use mason jar lids for the hoard of mason jars I have accumulated in an effort to reduce waste.
