Query: melamime bowls

the bowls arrived broken. and beside that, they are plastic. I did not know that. I thought melamime was part of the name. upon further scrutiny of the item specifics, it does indeed say they are made of "sturdy melamime. it should clarify that they are plastic!!I should not be expected to know the chemical breakdown of different types of plastic to have been able to identify "melamime!! 3$ per plastic bowl that I can purchase in the dollar store or walmart. :(
