Optical Illusion Grinder

Seeing that you're on this page, it seems you may be... eyeing this grinder? All jokes aside, this is the perfect example of a simple grinder that gets the job done, while sporting an interesting design. This is a 3-piece/2-chamber grinder: Herb is ground and held in the top chamber, and kief collects in the bottom chamber. The 3D domed eye can be seen from all angles!
