Hello and good day, the original cartridges are not in the featured package - delivered, but more or less carelessly together in a neutral small box - ie individually in their original box. And so they do not durcheinanderpurzeln during transport, just a small piece of crumpled paper was done to it. So you can not see the control numbers, nor the date of manufacture and expiry dates. Add to this that the el. Contacts are completely unprotected. As the cartridges achieve their intended service, I can not judge at the moment, since they are intended as a reserve. So, since the supplier must go in times and consider something. How to Me. F.Markmann
