- The flat-bottom batch paper for Fellow's Aiden, sized for 8-12 cup brews in the flat-basket family. The wide, flat bed is the batch-brew geometry; it fits flat-basket seats and interchanges with other basket papers of that fit, not with the Aiden's single-serve cone. Fellow publishes no flow class, so we leave flow unrated. It's an everyday single-use paper with no special care beyond seating it flat.

- How it brews
- The flat-bottom sibling of the FAST cone: a smooth, non-fluted paper using the same abaca technology, sized S (≈Kalita 155) and M (≈Kalita 185) for wave-style flat drippers, plus a larger size for basket machines. Because the wall is smooth rather than pleated, Sibarist markets it as keeping water in even contact with the whole bed and reducing bypass while still draining fast — a mechanism claim from the maker, not a measured result. It drops into a Kalita Wave 155/185 seat, so it's an option anywhere those papers fit. Single-use, made in Barcelona.
