Its a large white box that looks cool when you drop three of them in busy old athens.
Whats not cool about htem is that they look exactly like everything else in the missions that they come in (bleach white hospital type missions). In these missions there must be what looks like 20-40 objects that are about the same size, shape, and color of the mission item. It makes runing/sneaking these mission much more tedious and difficult.
I say keep the size and shape, but just make it some crazy color, lke that hiedious color of the agil/sense cloaks! Thatll make it stand out!
