Query: Don't buy this

I bought it before my kid was born... Now we opened it to use, and it turned out all the cups have been used!!! They do not look fresh, and seems that they have been washed by hand (and not very well). Only one set of cups and spoons were clean as new. I have thrown away all the others. I would give 0 stars if it was possible. Don't waste 10$, it's a gamble.
