Wholesale, it would usually come in a labeled box with a summary on the back and a disk that has the names and ect on it.
These are DVDs, menued (usually), with all of the episodes on it. It comes in DVD sleeves (see below) to lower the shipping rate (so they say). The DVDs are entirely blank on the front but their label.
I don't really know, but there is a chance this series has never been made into DVD counterparts. This could mean the copy on the DVDs here have a trademark sign on a corner, or slightly less quality, because it has been ripped from it's original copy. Also, there was probably never a subbed version made by anyone but fans, so there would be no english copy but this type of dvd.
Anyway, for around 10$, I would go for it if I were you. Then again, I don't much mind what my anime looks like as long as I can watch it. >w>
