Frixion stamps exclusively sold to Taiwanese pilots. These stamps are like magic, disappearing when rubbed! You can erase mistakes! They are the same as the familiar Frixion stamps in Japan. This product is an authentic item purchased in Taiwan. I think it's rare to have a case included. This set of three includes tapioca, Taiwanese banana, and a motorcycle. *Please consider this item with the understanding that it has been stored at home.
