I have a few. Mine are mostly characters that I collect. Tinker Bell & Peter Pan and gang, Pinocchio & Jiminy & Gang. I have found very few Alice ones, and none of Sword in the Stone.
I have found them at WDW, DL, Toys R us and other toy stores. Sometimes stores sell them in packaged sets. I have a couple of Peter Pan ones that came in a video like package, they are from Japan. Also some older Happy Meal toys used to be made of this PVC material.
Japan has sold some in machines, like we do here with candy and bubble gum. Those are cute.
Toys R Us has had some for $1.00. The ones from the parks are usually $3-$3.25 each. The sets are about $10 depending where you find them.
Very cute inexpensive (for the most part) collectibles.
