One of the great features of a Vipp Trash Can is its ability to hide the trash bag liner. This done by having a can inside a can, with the garbage bag lining the inner can. When the Vipp Trash Can lid seals shut, it closes the outer can. Brilliant.  Naturally Vipp spent a little time thinking about how to make better trash bag too. Each Vipp bag size is customized for each of Vipp's inner trash cans. The trash bags are available in five matching trash can to bag sizes. Vipp bags have a soft nice to the touch feel yet are incredibly strong. Each size bag has been designed to maximize the size of its container and the bottom of each bag is reinforced. If you have ever put a store bought bag in a round trash can, you will be amazed how well Vipp Trash Bags work in their perfectly designed counterpart.  All Vipp Trash Can Liners are sold in 16 roll cases.
