Thank you for viewing. This is a set of two passbook cases and a stamp case featuring a Hello Kitty design in collaboration with the post office. Large: 22cm x 12cm Small: 15cm x 11cm (Please note that these measurements are approximate.) The passbook cases are unused, but the stamp case has been opened and a stamp was placed inside for testing. Please refrain from purchasing if this concerns you. Also, please be aware that the ink pad inside the stamp case may be dried out and unusable due to the passage of time. Please consider this before purchasing.
