I met my favorite baseball player, Jack Wilson, of Pittsburgh Pirate fame, today, and he autographed my J. Wilson t-shirt. However, he didn't sign it with the traditional sharpie. Instead, he signed with this silver pen. I was too excited to take notice of what kind it was at the time, however, my sister did capture it on my digital camera. Sadly, I cannot figure out the brand from the picture.
Does anyone know what kind of marker this pen is? It's silver, and it had a silver cap. Can anyone give me any information on it? Brand, washability, etc. I don't want my autograph to wash away!

*EDIT* We think we figured out what kind of pen it is, now.
A Sanford Silver Coat Marker. Anyone have any experience with washing with these? If not, I think I'm making a trip to the store soon to get one to test out on a shirt.
