I know what it is but I won't spoil it for you. Congrats on a discontinued model. 
All my packages from Katsu-san arrived within 3-4days as well. Not sure why yours took 1 week. Maybe the customs officers wanted to have a good look at it. 
No, the box was still intact with the JP label still intact. I thinks its because the item reach another city instead of the city in my area. Something like I am in Ipoh while the parcel reach KLIA.
