This steel trash can features a double gasket to contain odors. It has a dial-type child lock. No special bags are needed; standard trash bags can be used. Size: Approximately 24.5cm wide x 35cm deep x 55cm high Weight: Approximately 2.3kg I purchased this new and used it for about 2 years. The entire item has been disinfected, but please refrain from purchasing if you are concerned due to the nature of the product. Also, there is no original box. It will be packed with bubble wrap and cardboard for shipping.
