A wrapped bundle of tobacco industry products is disclosed. The wrapped bundle has a barrier material sealably wrapped about a group of tobacco industry products such that a pressure differential exists between the interior and exterior of the wrapped bundle. A tab is arranged such that pulling the tab separates the barrier material to form an extraction opening. The barrier material and/or the tab is configured such that when a user pulls the tab an initially restricted opening is formed in the barrier material which is arranged such that said user is able to detect the fluid movement through the restricted opening as the pressure differential is equalised. |
