Since its first release five years ago, the Knock Aergrind Grinder has been redesigned for better stability and alignment. It has also moved to be COMPLETELY plastic-free and now features a gorgeous walnut handle. Your Aergrind coffee grinder comes with pink and orange bands that you can switch out according to your style and mood.
