In my opinion the XS pop - top jars aren't for storage if you want your medicinals kept fresh! They are clear glass...not good as soon as unfiltered light enters it immediately starts to degrade your herb. Whereas the Herb Preserve jars are made from Miron Glass used in the pharmaceutical industry. This picture shows the effect on a tomato stored in a clear glass jar and one in the herb preserve jar
I spoke to the manufacturer of these herb preserve jars and they would be willing to not put the labels on the outside if people want them that way. Also hoping that they would honour the 2 free jars offer too with the drop making a total of 5 jars.
