This is a vintage American cup and saucer. It's oven-proof, so it's heat-resistant and safe for microwaves and hot items. The temperature range is listed on the box, so please refer to it. Size is indicated in the photos. The condition is deadstock, so it's really good. I've taken as many photos as possible. Please check the photos and purchase as is.
