The nipples are of excellent quality and good looking. They have rubber grips for invisible socks, but they are very big. They will never fit a 2 year old. Maybe I misunderstand the size. This may be because they are stretched over a piece of cardboard shaped like a foot that is quite large, over an inch longer than my 2.5 year old foot. I will wear them until she grows up because she likes them and they are good quality.
