I have never started a thread like this before, so I hope I am not beating a dead horse on this one. I know there are tone of threads out there discussing the creation of magic items, and I have read through them, as well as reading the book, AND other sources online.
While a lot of magic item creations make sense, there are a lot that don't calculate in my head. When that happens, I usually try to "reverse engineer" an item to see if I can figure out how they got there.
One that I am having an issue figuring out is the Efficient Quiver

Would someone be able to help explain to me how an item like that, needing a 9th level caster and a 5th level spell and having no space limitation costs only a mere 1,800 gp?
Thanks all!
(as an aside, the reason I am asking is because I am trying to throw together a similar magic item...)
