OREA V4 WIDE coffee dripper with matching negotiator tool for flat filter papers. This dripper is made of plastic and has a metal base. By changing the four different bases, you can alter the coffee extraction speed and bring out different flavors. The negotiator tool fits perfectly inside the dripper and can be used to set flat, circular paper filters. You can also swap the tip of the negotiator tool to combine it with the dripper's APEX base to create a conical shape. Thank you for looking.
