Does anyone ever have that instance when you first open a toy and it feels...slippery, for a while? Eventually, it goes away, but some toys when I first open them they feel slippery or "oily" in my hands. Today in the mail, I got Hasbro's 10th Waspinator and Takara's 10th Dinobot. Waspinator seemed normal, but Dinobot felt oily. Is this because of the kind of plastic, or paint applications, or what?
