Here we have a nice used far right passenger side dash air vent.  This was removed from a 2014 Toyota Prius and may work for other years (2010 - 2015 perhaps).  I don't know which other vehicles it may fit, so please look at the pictures to make sure it is the exact same item that you are needing.   It is in good shape and the louvers all move nicely as expected.  I think there are different versions of the Prius so the vents may be different depending on the exact model so please compare this part to yours to make sure it is the one you want.

 
Shipping is included in the purchase price and I generally ship via the US Postal Service parcel post (unless Priority is almost identical in price) but I may send it via UPS Ground instead of USPS as sometimes the costs can vary considerably depending on the delivery address.  I will ship Internationally but only if the buyers shipping address is in the eBay Global Shipping Program list, no exceptions.  Please realize that depending on where you live, you may have to pay sales tax when purchasing, this is not a payment that I receive and I have no control over eBay adding this cost, and it will show up when the buyer pays for the item.
