Box made for ecommerce, with locks at both ends. Return of goods in the same box is possible twice, without using tape. After using the package the first time, the customer can rip off lock 1 and use lock 2 for return. Returnable packaging for goods bought on the internet has been a problem until now. This box gives the buyer the ability to reuse the package, even without tape. "Smart Lock" is adapted to the Norwegian postal services dimensions for boxes.
