It comes in a pack of three.
From left to right these Pokemon are: Tepig, Snivy, and Oshawott. Tepig is the fire type Pokemon, Snivy is the grass type, and Oshawott is the water type. In the game, I chose Oshawott. A-ee bought the set for me.
I use the red stylus and the green stylus sometimes. I always use the blue stylus with Oshawott because for me that Pokemon is the best and the cutest.
You can use the three of these on any kind of Nintendo DS, like DS, DSI, and DSI XL.
