The Bonmac dripper gives you, the professional barista or home barista, total control to make the best coffee that in itself is a work of art. The reason is that the dripper has a single hole that can slightly increase the dwell time and also control the coffee flow. An added bonus is a view slot so that if you're brewing directly into a cup, you can see how much coffee you've made. Total control over how much of your favorite coffee is being made to your high standards. Experience the best way to make pour-over-drip coffee.  & bulk pricing are available.
