Query: Don't buy unless you want pieces of plastic in your food

I used these with no problem for a year but then noticed that the inside of the bowl used most often was scratched by the whisks of my mixer. I didn't even realize it until I was whipping heavy cream one day and noticed teeny tiny red plastic chips in my cream. The cream was full of little red particles coming off the sides of the bowl while mixing. I wonder how many times I ate those plastic particles not noticing if the food mixed in them was darker. I threw all the bowls out at an instant.
