Multipiece Natural Stopper ???
Multipiece natural stoppers are manufactured from two or more halves of natural cork glued together with an adhesive approved for use with food. These are stoppers made from thinner cork that would be insufficient to make natural stoppers from a single piece. These stoppers are of higher density. Whether in more common sizes or in the existing classes, they are basically the same as single piece natural stoppers. The multi-piece stoppers are used more in larger bottle sizes that require larger stoppers, which are harder to fabricate from a single piece.
