Dear Miss Luna,

Wherever did you find a Wrinkled Witwizkie? This is by far the most perfect shell I've ever seen! It is text-book perfect! Thank you for this very generous gift!

I can set up a port-key if you'd prefer, instead of international apparation. I've verified your application with the regional Ministry of Magic Office, and they said it is approved. Just waiting on your chosen date of arrival—I'll be there to meet you.

Eagerly awaiting your arrival,

Rolf
