Otto's patented AI grinding system analyzes your material and automatically adjusts the direction, speed, and pressure of the precision-engineered milling blades.

This ensures the perfect grind for every grind. Otto mills your material in the expandable chamber, cutting it layer by layer to maintain quality and texture. Once perfectly ground, Otto ensures the material enters the Cone cleanly and evenly, fully preserving leaves, oil and resin.

This stylish all-in-one machine can grind 20-30 premium cones per load and automatically packs them with consistent efficiency. The Otto Grinder turns dried material into cones in seconds. Banana Bros. equipped Otto with a spring grinder for consistent and perfect grinding of the contents.

In addition, 20 premium cones are carefully rolled by hand. Their size and shape allow for seamless filling, the solid twist design prevents unintentional bending, and the whole thing is topped off with an optimal airflow and combustion process. The cones are made in Bali from 100% natural raw fibers and contain no GMOs, chlorine or animal products.
