About tenso package

[CeReSu]

Hi!

I have just received a mail from tenso! I have a new package from AVEX:
Look:

-- Package information (1) --
　Sender　　　　　　 : エイベックス
　Item (description) : Books
　Number of items　　: 1
Weight　　　　　 : 20 g

Does anybody else received this mail, too?

As usual, the sender is Team Ayu, so here is avex...so I think it's just...curious xD

Thanks!
