The Anaxy grinder is an anodized aluminum blade style grinder that not only stashes, your herbs but it also grinds and dispenses it. Simply put it in the top container and start grinding. When you're ready, inset the tip in that end of the pre-rolled paper and fill it up.
The fact that you can open it to disassemble it makes it easy to clean. It also has a measuring cap which lets you dose your herbs. It uses a 2 strong neodym magnet to close the two portions together.
