Hussalo"Note: As with all sealed Magic: the Gathering products on Massdrop, we are limited to shipping to addresses in the United States. This drop is limited to 1126 booster boxes."
So yes, it is sealed.
Hussalobought from mass drop before. they are legit but it does take a while due to them getting all the orders in order after drop ends then they order straight from the distributor themselves which will take some time and ship them off to you. dont expect to see the box till like nov 20th+ but at 20-30$ less cost for a bit of a wait. im ok with that
So yes, it is sealed.
