How do I combine the pen and the package? I'm at the cardinals study and can't seem to get those together.

Before you can do this:
Check the trolley with Vatican posts. Sylvie states that the stones be better mailed using the Vatican posts.
Look at the sealed package you made. You will note that it needs an address.
Do the addressing only when the cardinal is gone.

Now you take the pen and click it on the package.

Thanks for your help. You guys always do a good job helping me when I get stuck.
