This funnel is made of durable, food-grade plastic. The smooth inner surface makes it easy to clean and sanitize. And the stem fits easily into carboys but is wide enough to provide fast flow. The funnel comes with a 5.5″ diameter, fine-mesh straining screen, and the interior has a notch around the circumference where the screen rests securely.
