looking for the name of a type of header

Basically its a strip of pins connected together with a piece of plastic. One side of the pin strip can be inserted into a PC board and soldered in place and the other could either get the same treatment or get pushed into a breadboard (the use I intend for it). Problem is the website I know of that useto sell them no longer does and I cant seem to find it on mouser since I dont know the right name of what I am looking for.
