From Bulbapedia, the community-driven Pokémon encyclopedia.
Bandai Friends are small Pokémon plush toys. They are only around three inches tall, and come in a box with candy. There are a variety of sets available. Each box usually depicts the set on one side, with the character purchased on the front of the box; they are not random. They come without hang tags, and only a small tush/seam tag. Some Pokémon, such as Mew and the Kanto starter Pokémon have been released more than once.
