A:AnswerThe lid from Target’s $3 Room Essentials 10 oz coffee cup fits this perfectly. I use them regularly because it helps maintain the temp therefore preserving battery life and keeps my beverage from being exposed
A:AnswerI have no problems with chipping that is why i picked the copper one on the advice from you tube, when you pour coffee or tea do not use a metal spoon in the cup.I have had the cup for a month now with no problems and no it does not feel ceramic. Wash by hand and completely dry it before putting it on charger.
