These "fat" bison tubes are an all new size. They are still about the same length as a standard bison tube but these are fatter than a normal bison tube. They measure just shy of 3/4" wide making them much easier to put a log sheet in. We only have these available in black. Pictured is a standard bison tube in red and the new "fat" bison tube in black. Each container comes with a Rite in the Rain log sheet.
