With the original 6 pack, there were two cups slightly smaller and made different around the rims. My daughter in law noticed this. I did send a message but no reply as to why this was being in a set of 6. In addition I brought an extra 2 cups to match the 8 plates I akk K do brought. I’m very happy with these products but really thought someone could have acknowledged my original question as to why 2 cups in a sold set of 6, were obviously made different.
