The plural of vinyl is vinyl. To discuss these figures with proper grammar one would say "vinyl figures"
I do love these figures, however they are so expensive. We\'ll see I guess maybe I\'ll bite. That said, the card behind Bumblebee showing the Cybertronian alt modes for Bee and Starscream look awesome! will gladly grab a set of them.
Not worth the money IMO. For around 100 dollars, it needs to transform and/or really detailed and posable. Unfortunately, these are neither AND overpriced.
