I bit into a piece of plastic of sharp black plastic when eating one of your malted milk biscuits. The address on the pack is Wellington street Batley WE17 5JE so it is your brand.

Absolutely ridiculous and dangerous. My young daughter could have been eating them luckily it was myself and did not swallow it as it was very sharp and about the size of a 5p piece.
