The Glass Jar grinder is another new addition to the EDIT Collection and brings another one of the latest features that people are incorporating into their grinders, a clear perspex window section that you can look through to see how much of you material is ground up and ready to go. This means you can keep an eye as you grind and stop when enough has fallen through, or just leave extra in there ready for next time and you can see straight away that you don't need to grind any more. The teeth are incredibly sharp and will slice and dice pretty much any herb material you put in there. At 2.2 inches in diameter it will also have plenty of space for grinding up good amounts of herb in one go. They include a plastic pollen scraper to clean out the lower section when you decide you need to use it for something aswell.
