The Collapsible JavaDrip's clever, expanding silicone cone brews fresh, delicious coffee and yet collapses to just 1-inch high to travel anywhere. Simply set the filter on top of your favorite container, from a wide mouth water bottle to a small pot, add any brand of #4 filter, grounds and water and voila, eye-opening drip coffee just like home.
