Otto Grinder

Rolling a joint takes time, can be messy, and it doesn’t always come out the way you want it to. If you'd prefer to throw the herb in a machine and let it do all the work, consider OTTO Grinder, the world’s first automatic rolling machine. This innovative piece will transform your flower in a ready-to-use cone with zero effort and in a matter of seconds. Perfect for newbies and perfectionists, Otto senses density, moisture level, and texture of your herb and adjusts its movement to deliver an ideal grind each time. It’s easy to use, effective and convenient, and the minimalistic design makes it a perfect decorative piece for every kitchen counter.
