Just to clarify, for those saying the rate of return in retail is high — which may be true and more so for online purchases — if something has been returned it USUALLY DOES NOT EQUAL USED. Many people return stuff because they don’t like the color, size, shape etc. and don’t try it (our concern is mainly cook/ eat hot food with it) first.
So bottom line, there is probably a percentage of used utensils that get sold as new, but it’s not so high either.
