Unlike traditional V60 drippers with which coffee is extracted through the constant pouring of hot water, this dripper is specifically made for immersion extraction. The metal ball placed at the base of the dripper  blocks water from flowing through, allowing the poured water to stay  inside the dripper. Then, with the push of a button, the coffee flows down into the coffee cup, allowing for easy, even coffee extraction.
The box includes a heatproof glass server (300 ml) and 1 pack of V60 filter paper (40 pcs).
