The spoons are now used regularly for over a year with us. So far there were no stains, discolouration or scratches in the metal, instead they shine and are smooth as the first day, even though they are always cleaned in the dishwasher. Unlike other coffee spoons we use, they are a bit more difficult, but this is not unpleasant, but rather the feeling of quality. All edges are pleasantly round, there is no disturbing degree. Even if it concerns teaspoon, they could be a bit bigger. For children's hands it may be a nice size for an average-sized adults hands the style is a bit too short and thin, so that the grip is suffering and the style hardly protrudes from normal large cups out. The capacity of the bucket is rather low. Thus, these are the smallest teaspoon which we have in the budget and are therefore less used to eating yogurt, pudding, etc..
Conclusion: The quality of coffee spoon is undisputed. The spoon feels very good and has something of a flatterer. If it were a bit bigger, it would be a perfect coffee spoons.
