This 10mm Tube Insert is designed for use with our King Kone Tube Conversion Kit, in order to provide you with interchangeable options to pack more 84mm blunts and tubes with your King Kone Pre-Roll Machine. This insert is perfect for any 9mm blunt tube option that is 84mm in length. Available in both hemp and traditional rolling paper. For accurate weight distribution, we recommend purchasing the 1/2 gram metering tray for perfect 1-gram blunts. Controlling your weight variable earlier in the production process saves you money in labor down the road!
