We use this type of cone filter holder when we're doing demos, to brew individual cups of coffee. We have so many requests from people asking where did you get that? that we decided to offer them here.

They're made from black plastic and sit right on top of your coffee mug. They accept a #2 or #4 cone filter.

Dimensions: 4-3/4" top diameter, 4" high, four 1/8" square drain holes. Dishwasher safe.
