One size does not fit all! simplehuman custom fit liners are designed to fit each of our trash cans perfectly so there is no messy bag overhang or bunching — and they never slip. With extra-thick plastic and double-seam construction, simplehuman's tear- and leak-resistant garbage bags are extra strong so they hold more, which means fewer trips to throw trash out. Strong drawstring handles make these 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 trash cans with the built-in 'liner pocket' system.
