A kit for having party in the public space. Champagne, snacks, cans, napkin, bow tie, all these things which participants need to take part in the party is in a round bag for each participant. The host puts the description with place and schedule in the round bag and sends it to all participants, and there is nothing to prepare for the host on the day of the party. Plaza, park, street, inside a train, roof of a building, all these public space turns into party place without anyone knowing in advance.
