Returning Ebay item without a box?

I recently ordered an item on eBay can be a month ago. I found Element broken now and I wanted to pay it back but I lost the box with this item, but I still have all the rest that goes with the item. Is it possible to return the item to get my item back or get a replacement? and how? The element is a Plantronics Discovery 925 … (How do I wrap for the return.?)

Have you contacted the person you bought it on ebay and see if they will even accept a return after a month u have? I would start first.
