The King Kone Tube Insert, available in multiple sizes, is designed for use with our King Kone Tube Conversion Kit, in order to provide you with interchangeable options to pack more sizes of tubes with your existing King Kone pre-roll machine(s). Go beyond the standard pre-roll cone sizes and offer diverse pre-rolled tube products with the help of this tube insert in 9mm, 10mm, 11mm, 12mm, or 13mm. We recommend ordering additional trays as well as tray sizes to not only better automate your pre-roll business, but also to get more SKUs out of expensive machinery you’ve invested in.
