Hi Wendy! Thanks so much for your question. While our mugs and dishes are dishwasher and microwave safe, they may chip and fade more quickly than items purchased in stores. With that in mind, we suggest that they are washed and dried by hand from time-to-time. (But I must confess: I put them in the dishwasher and microwave regularly :-) Josie
Several of the items are, they will be marked.
Thanks! Your answer is awaiting moderation.
