Hello, I researched these pieces all over Bricklink and I used every trick I had up my sleeve to find them, but sill no luck. I am hoping that the folks at Eurobricks can help me instead.
In the first picture: My friend gave me these so I could find out what set they are in. I believe they are broken because I think the top and bottom of them should be full circles.
In the second picture: I looked through every single door on Bricklink and still could not find this one. I even doubted it was Lego for a while but my friend says it is.
In the third picture: I got this pink heart in a bucket of Lego a while back. I strongly doubt it is really Lego, but the thing that made me unsure was the fact that it fits perfectly in a Lego Minifigure's hand.
Thank you for all your help!
