Giannine, I think you are referring to the white bell in the background? That's the biggest, heaviest one he has. The one in the foreground is a bell also. He loves his bells. From what I read here, all greys do. I got those at the bird fair a few years ago. They are heavy, bird-safe, and he can't get to the clapper to chew it loose.
As to where to buy the cup set, I would think you could get stainless steel measuring cups about anywhere that sells kitchen supplies. They will say "stainless" on the bottom of the cup.
