Simplehuman Bin Liners 35-45 Litres | Size K | 20 Pack Simplehuman custom fit bin liners are designed to fit our bins perfectly, so the bag stays completely hidden when the lid is closed. The custom fit also means the liner fits tightly around the inner bucket and won't slip into the rubbish. Available in a range of sizes, these liners are made from extra durable plastic with thick double seams to prevent rips and tears and convenient drawstring handles so they are easy to lift, tie and carry.
