I don't have an answer to the question, just a problem, and unfortunately no other way to write to you, I used to have the green version of the Topline yoghurt box. It broke and I bought a new one. I am not satisfied with the new version. It is very difficult to open and close. I have a lot of trouble with it and could imagine that the older generation won't be able to open or close it. I would like to have the old green yoghurt box back. Thank you for your reply. Kind regards Christine Rütti
