This is a set of 12 photo cards, not postcards. They feature images of Red Fuji, Diamond Fuji, Fuji at sunset, fireworks, and rare skunk cabbage, among others. They are as thick as postcards, and larger than postcards, all the same size. 13cm tall x 18cm wide. Each card is individually sealed in an OPP bag. There are no tears or stains. I do not have any pets. I am also a non-smoker.
