Crafted from brass in a victorian style, The Explorer utilizes the Hario V60 glass pour-over cone (included) resting on the ring to adjust to the height of your mug or decanter. The ring adjusts using the telescoping arm (11 inches tall) to the height you need. The base is made of beautiful American Walnut finished with simple food safe coating. The ring can accommodate a number of other pour-over cones and bases.
