Hope Forever Blossoming Vases
Packable, mailable, and otherwise generally easy to transport, these plastic vases by the Japanese company Hope Forever Blossoming are held open and stable with water and fold flat when empty, making them as clever as they are usable. Filled with flowers, they make an excellent gift that safely minimizes hassle on subways and in cars. Or, slipped in a suitcase, they add a romantic touch to hotel rooms that's a far better alternative to balancing stems in water glasses.
Pick up a set of two for $25 from Flight 001.
