QUESTION Are these microwavable and dishwasher-safe ?
Can you recommend such a hot mug which is very durable (against dropping) ... etc. ?
ANSWER Hi. This is made of ceramic, so it is microwave and dishwasher safe. It's durable, but like any ceramic item, it can get damaged if you drop it on a hard surface. If you want something more durable than ceramic, please take a look at melamine or polycarbonate drinkware, such as 383755. Thanks!
