Hey, Alan! Could u please tell me about the funnel. A lot of people use it for coffee (I mean they grind beans and after use funnel). But shape of funnel is fit with bottom of AeroPress, so u can use it for brewing also. Am I right? – From Marina A.

I designed the funnel to help pouring of ground coffee from a grinder bin into the AeroPress chamber. It was a coincidence that the AeroPress fits into the funnel. Some people have used it to press into a small cup. That's dangerous. Always press into a sturdy mug.
