## Abstract

A bin formed with a general circular shape in plan being formed from an outside liner of paperboard and an inner paperboard flute providing medium which is affixed to the outside liner. The flutes of the flute providing medium are larger than those of "A" flute. A removable sleeve interior, an optional base and lid are provided together with methods of carriage using same.
