The Futurola Knockbox is designed to work seamlessly with a wide range of pre-rolled cones, ensuring a perfect fit and efficient filling process. Here are the details about the cones that are compatible with the Futurola Knockbox: Futurola Pre-Rolled Cones: The Knockbox is specifically designed to work with Futurola's own pre-rolled cones. These cones are crafted with precision and made from high-quality materials to deliver a consistent and enjoyable smoking experience. These pre-rolled cones fit perfectly into the Knockbox, making the filling process smooth and efficient. Other Compatible Cones: In addition to Futurola's pre-rolled cones, the Knockbox can also be used with select pre-rolled cones from other brands. While the Knockbox is primarily designed for Futurola cones, it can accommodate various sizes and styles of compatible cones, ensuring versatility in your pre-roll production. We recommend consulting the Knockbox's user manual or contacting our customer support team to determine the compatibility of specific third-party cones with the Knockbox. It's worth noting that the Futurola Knockbox provides the best results when used with Futurola's own pre-rolled cones. The combination of the Knockbox and Futurola cones ensures optimal performance, consistency, and efficiency in your pre-roll production process. However, should you choose to use other compatible cones, we recommend conducting a small test batch to ensure they fit securely and work well with the Knockbox's filling mechanism.
