Smokers of all creeds (tobacco or herbal) who like to roll their own should appreciate a storage jar that helps keep its contents fresh. 420 Science agrees with me and has a wide array of jars/containers in a myriad of sizes and styles. 420 Science has been making storage jars for quite some time now (15 or so years!) and have a massive website full of products. I admire what they have achieved and rate a lot of their products.
