FLATS "Hatodan" was specially made for a handmade wedding ceremony held in an abandoned school building (former Nishi Musashi Elementary School) that is used as a FLATS manufacturing factory. On the day of the event, colorful "dove-dan" tied to balloons floated around the reception venue to congratulate the bride and groom. In addition, all the attendees took home a "Hatodan" assembly kit as a souvenir, which was very happy for everyone. It is truly a bird that carries happiness. Subsequently, many people who saw the state of this wedding in newspapers and on our website requested the commercialization of "Hatodan", and we decided to release this "Hatodan". For various celebrations such as marriage, childbirth, and birthdays, "Hatodan" will be the best gift.
