Fino's Number 2-Size Collapsible Silicone Pour-Over Coffee Brewing Cone is uniquely designed for compact storage and easy travel. It brews 2-6 cups of coffee without an automatic drip coffee machine. It measures 3.5 inches when fully expanded and collapses to just 0.75 inches high, making it the ideal coffee brewing accessory for hiking, camping, RVs, offices, small kitchens, and more. It's super easy to brew the most flavorful cup of pour-over coffee on the go. Expand the Brewing Cone, set it on a mug, pot, or carafe, insert a reusable or disposable coffee filter, and measure in 1 rounded scoop of medium-grind coffee per serving.
