I've been looking for some storage jars, the Jyarz look good, but the tall/slim profile doesn't fit in my storage box as well as the wide/short shape. I have some small glass jars with plastic lids (similar to those sold by specialtybottle.com ), but they're not really odor proof, so I'm losing some of the moisture from my herbs. Somebody mentioned Cooljarz in a post, so I looked them up, very reasonable prices, claimed odor proof. They are plastic (food-grade polypropylene). Can't find any reviews here or elsewhere as far as their ability to keep freshness in Anyone have any comments on them?
