Doob Tube Flexible Funnel
This flexible funnel was designed to perfectly fit over a standard Doob Tube to assist in loading. Current funnel has a 40mm diameter (1.57 inches) but can be adjusted to fit any size grinder if necessary.

I love this funnel! Not only does it work with doob tubes, it also fits perfectly as a loading funnel for my Sticky Brick Jr.
