The 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 cans with our built-in 'liner pocket' system.
