The OTTO™ by banana bros.™ is a sleekly and ergonomically designed all-in-one device able to mill and fill 20-30 cones per charge, automatically and evenly. The OTTO smart mill transforms dry material into a cone in seconds.  Employing their own innovative SMART milling technology™, banana bros. equipped the OTTO with a spring-loaded mill that mimics human hand grinding gestures, ensuring that content is ground to uniform perfection. 

This all in one tool was engineered for convenience, the OTTO combines the functionality of an electric grinder and automatic cone roller in a single device. No more relying on multiple tools to prepare your dry herb for cooking or smoking. This travel-friendly powerhouse will grind, fill and roll your dry material in one fell swoop--all with the push of a button. You can quickly roll a cone whenever you want, or stock up so you always have a smoke ready. Equipped with patented SMART grinding technology, the OTTO automatically adjusts to the optimal grind for whichever herb is loaded.

Premium Cones

The OTTO comes with 20 premium cones that are carefully hand rolled for reliable performance. The lip of each cone is sized for seamless filling, and a sturdily rolled design prevents bending and runs to promote optimal burning and airflow. To ensure a higher level of purity, banana bros. uses 100% natural high-quality raw fiber. Crafted with care in Bali, each cone is free of GMOs, chlorine, and animal products. Expect full flavor, aromas, and effects from each recipe or draw with a slow, even burn.

A Sleek and Functional Design

The OTTO's minimalist aesthetic is both sleek and functional. A single button with an LED backlight gives you easy mastery. The chamber features a high grade, wear-resistant metal teeth perfectly aligned for shredding dry herb down to fine granules. An o-funnel ensures steady, spill-free loading, while a transparent cone tube allows you to observe your cone as it fills up with dry material. Equipped with an airtight seal, the OTTO prevents odors from escaping the tube, ensuring a stealthier experience. A magnetic connection enables swift, snap-on attachment for easy retrieval of your freshly rolled cones, while a USB port enables rapid charging from a variety of power sources. The OTTO by banana bros. is the ultimate mill and fill all-in-one tool for connoisseurs.

How To Use the Otto

Using the OTTO makes preparing your herb a simple, intuitive experience. Simply load the chamber with dry herb and place a premium cone in the tube. Attach the grinder to the tube using the magnetic connectors located under the device. Hold the power button down to turn the device on, then press it once to begin grinding. This innovative electric grinder will sense changes in the material and make adjustments to ensure perfect consistency. The cone will then be evenly filled with ground herbs. Now just retrieve your herb and get ready to cook or your cone and get ready to relax.
