New in open package.  433MHz Wireless 16-Channel Flash Remote Trigger with Receiver for TT850, TT860 Speedlite. Remote trigger will work on any camera with a hot shoe regardless of brand, but the receivers are intended for use with Neweer-brand flashes - I can't see any way of modifying them to work with another brand... 

A good deal if you have (or plan to buy) Neweer-brand flashes!
