Friends TV-Series - Vintage Symbol Coasters (Warner Bros., 1999)

4 quirky coasters, with designs that make no sense, but that are just super 90s. What were they trying to signal here...?
Oh, maybe it's supposed to represent the characters! Oh yeah, that totally makes sense. 
So we got: 

- The Heart: Obviously Phoebe, because she is so full of heart. 
- The Waves: That must be Rachel, because her mood is like the ocean - unpredictable and scary!
- The Star: Joey, the star of the Joey, since he got a spinoff. 
- The Mug: Probably Chandler, since he has an ugly mug (jk hehe).  

We're 99% sure this is what they meant. Or maybe they just went with popular shapes and put the logo on it. Either way, they're cool! 

Condition: Great!
