Is this real or fake?

Today during a Jelly king run I got mail from someone. It seemed very odd to me. See this photo and you will know what it says: http://cloud.steampowered.com/ugc/505763950861568284/588A78C343CD49BCAAE...
The reason it was odd to me because I do not recall getting a proto sword.
Any sort of reply that isn't trolling is appreciated.

I Guess they didn't want my Gel Drops. ;-;

Thank you two for answering my question. I guess I got that from when I started this regifting thing in my guild .

Wow, I'd ask them to keep the sword but give back the 25 + 100cr wasted sending a mail with attachments.

lol, you should leave it unaccepted and see where it goes after 30 days :-D

Oo you can send proto sword in a mail?

I second Nordlead's suggestion.
Maybe it'll be trapped in an eternal limbo?

Yeah I am never going to accept it. Also Asukalanforum I could send one to you if you wish.

@Juances - you only pay 100cr when a mail has attachments, and 25 if not. They don't add up.
@Asukalanforum - of course you can send an unbound proto sword in mail, like any other item.
Seems like at some point in the past you sent a mail to someone saying "Here is a gift" and attaching a proto sword. The attachment was never accepted by the recipient and after the mail was deleted after 30 days, the Spiral Postmaster returned the attachment to you, the sender.
