Ufotable's web shop recently updated their
special Fate/ZERO BD Box 2 page with a sample image of their own special deluxe carry box that will hold the sign board and BD boxset. What's even more scary is that the listing states the total weight for their set will be around 6KG!
Box 1 I ordered from Animate weighed in a little over 2kg with all the store and manufacturer's exclusives packed into two big boxes folded together. I can only imagine the eye popping EMS shipping charge will be with Ufotable's one, yet despite this, I've decided I will be getting a 2nd copy of box 2 from them anyway. That carry box and sign board is too good to pass up for me!
