One size does not fit all! simplehuman liners are designed to fit each of our cans perfectly so there is no messy bag overhang or bunching - and they never slip. Extra-thick plastic and double-seam construction prevent rips and tears. Strong drawstring handles make the liners easy to lift, tie, and carry. Refill packs dispense liners one at a time - no perforations or unraveling - and are designed to fit perfectly inside simplehuman cans with the built-in 'liner pocket' system.
