Ex Input:
I bought this for my son for Christmas around black Friday. It said it might not be here for Christmas so I wasn't holding my breath. The seller sent them out immediately and I had them in my hands much sooner than I expected. They are great quality and my son loves them!

Ex Output:

Ordered this case but two whole packs (4 individual) were rotten. I could even smell it right through the cover. At first I thought there must be a puncture of some kind but could not find any. So knock off 2 or more and that is how many one gets for the price.

These came in a huge box with other things that were glass!! The box was so big this poor little bottle just went from one place to the next in that huge box!! I'm surprised they weren't broken all to pieces. Not to mention there was a gaping hole where the tape didn't even catch !! I could stick my hand inside the box while it was taped!!
