Cube Letter Set


These whimsical blow-up letter cubes are created by Kouichi Okamato of Kyouei Design as a new take on the traditional Japanese paper balloons. The concept is simple; you write a message on a paper cube while it’s flat, and send it using one of the supplied envelopes. The recipient then blows it up into a cube-shaped balloon to read your message.

Each set includes one large and two small cubes, with corresponding envelopes in a sealed package. The cubes are made of lightweight translucent origami paper and printed with faint blue lines.
