Simplehuman 40 Litre Slim Plastic Pedal Bin - Grey
The perfect combination of quality and value, the slim plastic pedal bin offers far more than the average plastic bin. Not only is it more stable, durable and attractive than traditional plastic bins, but the lid can be locked shut to prevent curious pets or kids getting in. The wheels fit flush with the body of the bin, keeping the shape slim and space-efficient.
