"Pegasus filters are made from quality paper from Japan. This paper creates limited flow restriction to enhance clarity and balance in the coffee. White filters are made with 100% oxygen bleached paper pulp. These filters are specifically designed to be compatible with the Hario Pegasus Flat Bottom Dripper, Size 02. More about the Pegasus Dripper: The dripper is designed to be easy, durable and perfect for people looking to hone in their manual brewing skills. It's great for beginners but also great for pros that are looking for a brewer with a flat bottom that creates more flow restriction. The Pegasus Dripper makes hand pouring more simple by relying less on variable control like pour speed, grind accuracy and method. Unlike the classic Hario V60 Dripper, this dripper features two very small holes at the bottom that restrict the flow of the brew. "
