The Simplehuman Semi Round 45 liters lets you collect waste from a small family and easily replace a full trash bag. When the lid opens, the stainless steel ring comes up. This ring secures and releases the trash bag. Open the trash can using the pedal, so you won't get dirty hands. No problem if you touch the trash can anyway, since the stainless steel casing has a special coating which means you won't see any greasy fingers or children's hand prints on them. Silent closing prevents the lid from closing with a bang after you release the pedal. Use the Simplehuman garbage bag code J with this trash can.
