The first kind is the long slender plume feather. They come in many different colors and also come in striped colors as well.
The second kind is a regular feather. These can be put in by themselves or as a combo with one of the slender plume feathers.
A bundle of 3 feathers at my salon cost $24, so I'm assuming the price is about that at other salons as well.
You can kind of see one of my red/black and white polka dotted feathers peeking out. I have two of these but one is hidden :)
