The Fill N' Fold 70mm Metering Tray lets you pre-measure and portion your ground material before filling with your 70mm Fill N' Fold Work Tray, helping you keep your pre-rolls consistent from cone to cone. It's sized for 70mm cones and includes two adjustable metering plates so you can dial in the fill to match your material and preferred density. Because fill weight depends on your specific grind and material, the tray is designed as a portioning guide rather than a fixed-weight measure. Most operators use it to lock in a repeatable target for their own blend.
