The same tabbed V60 cone in 01/02/03, but made from natural, unbleached pulp — so it's brown rather than white. That bleach difference is the one objective distinction from the standard white V60; retailers describe it as FSC-certified and made in Japan without glue. Whether the natural pulp drains faster or slower than the bleached version is not something Hario states and community reports are mixed, so we leave flow unrated rather than repeat the "natural tastes papery / drains slower" folklore. As with any paper, a pre-rinse settles the bed and warms the brewer.

How it brews
The Graycano is a conical cast-aluminium dripper, and the GC01 is its own size-2 cone paper tuned to the dripper's "Lava Rib" geometry. Graycano states that V60 size 02 and Melitta 102 filters also fit the dripper, so we record a V60-cone seat as the closest match; the GC01 is a true cone. No published flow rating, so flow is left unrated. (This is the standalone Graycano brand, not GINA's cone papers.)
